some specific POSIX behavior is hard; and convincing them to change,
instead of fixing the buggy OS, is even harder. But that's OK, no one

standards enough that your applications start breaking.

correctly. Look at all of the work that's gone into the kernel to
make Linux's threads support POSIX compliant, for example. We did

LinuxThreads, even if certain aspects of Posix threads are a little
