I'll try to devise a fix for PosixProcPrim.
That's ECHILD, not EINTR. The only nice way to figure this out might be keeping a global counter (in an MVar), increasing it on forkProcess() and counting it down for each "awaited" child. That way, you could safely loop on `waitpid' if you know there should still be a child around (and you'll get `Nothing' if it's not done yet).
