So the make process gets an EAGAIN on the write syscall and doesn't
retry?  That sounds like a bug in whatever make you're using, since
that could potentially occur in other circumstances too.

(Same goes for EWOULDBLOCK, as well as EINTR if you don't have
restartable syscalls).

usually comes from bad judgement.
