If the sem implemenation on openbsd is similar to
http://fxr.googlebit.com/source/lib/libc_r/uthread/uthread_sem.c?v=NETBSD-CURRENT
it could cause other issues. Maybe on such systems it would be better to use
pipe(2) and implement post/wait with write/read on the pipes. It will use 2
file descriptors, though, if the system doesn't provide other robust
alternatives...
