I'm not sure that this is a good idea (esp. considering that sched_yield
on POSIX systems is not well-defined - it depends on your scheduling
policy).
On most OSes, this should be a no-op (as the OS should be handling
this via preemption). I'm not a fan of adding apr_thread_yield()
throughout to support a poor OS scheduler.
So, -0 from me (I won't stop you, but I don't like it). -- justin
