11.13 wakeup socket disconnect causes havoc
waking an iPad breaks the wakeup socket pair, triggering a POLLIN event and
resulting in SOCKERRNO being set to ENOTCONN.
This condition, and other possible error conditions on the wakeup socket, are
not handled, so the condition remains on the FD and curl_multi_poll will
never block again.

11.14 Multi perform hangs waiting for threaded resolver
If a threaded resolver takes a long time to complete, libcurl can be blocked
