So I tentatively submitted a test case to the Linux kernel mailing
list. I didn't know what to expect; maybe more flames carrying
over from the BFS debate? Instead, I got "Thanks a bunch for the
nice repeatable testcase!" This is one of the few times I've seen
this outside of what I attempt to do with x264: a developer happy
to see someone report a bug with his code and apparently eager to
jump to fixing it. Though it certainly sounded good so far, but
would anything result from this?
Answer: yes: up to a 70% increase in performance, committed the
next day. But the kernel devs weren't done yet: a quick grep of
Linux kernel mails over the next weeks showed x264 popping up in
quite a few scheduler benchmarks: they had added it as a regular
test case. And just recently we got another 10% performance.

Something that looks like crap should not get extra protection to
stay in the kernel just because it 'might' be non-crap.
