- Don't check errno on wakeup socket if sread returned 0 since sread doesn't set errno in that case. This is a follow-up to cf7760a from several days ago which fixed Curl_multi_wait to stop busy looping sread on the non-blocking wakeup socket if it was closed (ie sread returns 0). Due to a logic error it was still possible to busy loop in that case if errno == EINTR. Closes #xxxx
