Once shown to work it can. The snag is that (presumably) Linux/glibc 
gets detected as having a pthread_yield() or whatever, and Configure 
test is not robust enough to find it does not work. If "you" can 
establish that sleep(0) _works_ we can add that to some linux hints 
file so that threads->yield starts using it.
