I pushed http://hg.mozilla.org/try/rev/975f4580e779 to try with the commit message Fast refcount take 2: volatile long on Windows. try: --build all --p win32 --u all --t all I expected this to give me only win32 builds, but in fact I got builds and tests for all platforms. I'm not sure why this is messing up, but maybe it's because I put "try: " on a separate line?
Actually, it looks like this was me being confused by what --build all does. I'll mark WORKSFORME and push my next commit with |try:| on a separate line. If it still doesn't work, I'll re-open.
