Aha! Good sleuthing. :-)

Yes. That would make more sense.
Both I don't think that code path (sys_write) has ever been called
before on a nonblocking socket. (Because we've always opened the
sockets before without O_NONBLOCK, since we've never called
`make-network-process' with :nowait t before from `open-gnutls-stream'.)
So ... is it possible that these functions that w32.c calls just
don't... quite work with nonblocking sockets?
