The problem is not handling EWOULDBLOCK. The problem is that after poll() says
the socket is ready, send() returns that error. It does not happen in any other
OS but the Mac.

The IO threadpool uses epoll/poll/select and when the socket is marked as
ready, it performs a synchronous recv/send, which is the one failing with
EAGAIN/EWOULDBLOCK on the Mac. Until now, we were not checking errors in this
recv/send and were just passing them back to managed code.

If I attach a patch here, will you be able to compile mono from sources and
test?
