And here it is.  The fix is quite simple.  It ensures that sys_write
exits before touching the socket if it is not connected yet.
Unfortunately I didn't find any documentation on winsock ioctlsocket
that would prove that this is indeed required.  But it seems not wrong
to me anyway.  (I'll try to search the wisock documentation tomorrow to
find some hints that lead in this direction, or maybe you know?)
