Okay, turns out processes don't work so well just yet. Two issues I saw: 1) output from the child python processes wasn't getting piped back into the parent processes. I think I had noticed this before and forgotten about it, but this is not a great thing to have going on in --verbose mode. Because of the way windows multiprocessing works, the processes don't share file descriptors, and so I don't get this for free. I think the thing to do is to send the log strings over the message queue. In general we only log a couple of messages per test in the worker, so it shouldn't do more than double the message load. At the same time, on the dbg 2 bot, everything was totally broken: see http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Win%20%28dbg%29%282%29/builds/1265/steps/webkit_gpu_tests/logs/stdio . So it's hard to conclude much from that.
reverted in http://trac.webkit.org/changeset/79641
I don't think it should block bug 34984 and I plan to clear the blocking flag on Mon 4/11. If you disagree, now would be a good time to speak up :).
okay, given the fix to the web server on windows and the logging fix in 58296, everything seems to work for me, so it's time to try again ...
clearing blocking flag.
