	What's the possibility of doing this similar to how we do some of
the other functions (dl_open comes immediately to mind)...make a
pg_sched_yield function and use that, which is built based on the various
platforms?

	Right now, I don't believe we have *anything* in place, so have
pg_sched_yield() return 0 (or an equivalent) for every platform except for
Linux...
