I think we are getting closer to the root cause of the problem. In w32.c (sys_write), it runs into the following error: if (nchars == SOCKET_ERROR) { DebPrint (("sys_write.send failed with error %d on socket %ld\n", pfn_WSAGetLastError (), SOCK_HANDLE (fd))); set_errno (); } Strange thing: set_errno returns with errno == 0. This because pfn_WSAGetLastError returns 0 as well. Now, if I do... if (errno == 0) errno = EAGAIN; ...just after the call to set_errno above, guess what: It seems to work! At least for me, it will be an exercise for tomorrow to find the reason why pfn_WSAGetLastError returns 0 in this case. *snore* Do you agree it shouldn't return 0?
