Re-do the broken-nice() patch to break less platforms. Hopefully none :P
Also note that it isn't just Linux nice() that is broken: at least FreeBSD
and BSDI also have this problem. os.nice() should probably just be emulated
using getpriority()/setpriority(), if they are available, but that isn't
worth putting in 2.1.1.
