These are two old patches that I never submitted because I didn't really
think they were useful except as cleanups. Recently, however, Alex Graf
mentioned some problems that Mac OS X has with iothread, and they sounded
to me like they were related to these patches. And quite surprisingly,
both of them were fixing bugs!
Mac OS X still has problems with iothread according to Alex's testing
(Linux times out in libata, and reactos likewise hangs early on I/O),
but at least the patches fix deadlocks and keep a responsive UI.

iothread: replace fair_mutex with a condition variable
