My Thoughts:
If code could possibly break trunk, even for a few hours, it should be
branched. The developer should work on that code, test it thoroughly,
and ask others to test, once it's confirmed working, merge it back to
trunk. Simple enough. The problem is many developers only halfway test
that a given change works. Or they switch tasks in the middle of
implementing something, leaving it half unimplemented.
The issue with branching to begin with was the fact that we had
38924384238 branches with XYZ feature that were incomplete, because
developers left, got bored and lost interest, or otherwise. Branching
should be done on the short term. Instead of doing an entire win32k
rewrite in a branch, rewrite a given function at a time. If you must
rewrite several functions, do so in your local tree and only commit when
things are working. Better yet: don't do large rewrites at all.
FYI the ROS isos on svn.reactos.org STILL fail to install properly on my
vmware machine. Formatting the virtual drive and attempting to install
crashes setup, installing without formatting results in locking at the
boot screen with just the little bar going, and booting the livecd also
results in a lock on the boot screen. These types of regressions should
not exist.

CHAPTER VII. THE FOUR CLASSES OF SOCIETY. THE FOUR CLASSES OF SOCIETY. "After the herald had given the names of the wrestlers who were to make the first round, the fellows came in. They were dressed without any clothes to speak of, or rather they were quite undressed, with the exception of a cloth around their loins. They came in on opposite sides of the ring, and stood there about five feet apart, each man resting his hands on his knees, and glaring at the other like a wild beast. They[Pg 231] looked more like a pair of tigers than human beings, and for a moment I thought it was not at all unlike what a bull-fight in Spain might be. I turned upon her choking with anger, but her melting beauty rendered me helpless. Black woods were on our left. "Shall we turn in here?" I asked. "None of that with me," he growled. "Do you know who I am, Countess Lalage? I am Leon Lagage, Count of the Holy Roman Empire, and your husband. Incomparable woman, you cannot alter that fact. For better or worse, for richer or poorer, till death do us part!" I have in this way imperfectly indicated a methodical plan of generating a design, as far as words alone will serve, beginning with certain premises based upon a particular work to be performed, and then proceeding to consider in consecutive order the general character of the machine, mode of operation, movements and adjustments, general arrangement, strains, special arrangement, and proportions. ‘Alas! what is life, what is death, what are we, 11th January two best dresses.

The next morning he was up betimes, and cooked the boys as good a breakfast as he could out of the remainder of his store and what he could get from the hospital, and then gave what was left to whoever came. The comfortable crib, which had cost the Deacon so much labor, had been pre-empted by the Surgeon for some of his weakest patients. "You two step forward one pace," he commanded. "Gentleman, I've got my six. The rest are yours." "Where are you goin'?" he said sternly. Every now and then the crowd would break into the latest rhymings of MacKinnon's poet: A large thicket, at this moment, gave the dusty foot an opportunity of doubling, and, for an instant, diverging from the straightforward course, though it availed him little, he seemed to feel the breath of his pursuer on the back of his neck; his foot sounded as if at his heels; he drew his garment closely around him, turned suddenly to the right, and, bounding from the ground, the next instant a splash was heard in the little river, and the fugitive was safe from his pursuer.
