I don't run Windows, sorry I'm no expert there, more questions than answers below... So apr_poll() returns APR_EINVAL, right? What could be the reasons for poll() in cygwin to return EINVAL? I don't know how cygwin implements poll(), but for instance I see that WSAPoll() can return: WSAEINVAL An invalid parameter was passed. This error is returned if the fdarray parameter contains a NULL pointer. This error is also returned if invalid flags were specified in the events member of any of the WSAPOLLFD structures pointed to by the fdarray parameter when requesting socket status. This error is also returned if none of the sockets specified in the fd member of any of the WSAPOLLFD structures pointed to by the fdarray parameter were valid. What's the value of "timeout" for apr_poll() in send_brigade_blocking()? Could you debug apr_poll() and see if something like the above happens to the parameters passed to poll()?
