[PATCH v2 2/2] server: Reselect only after dequeueing async request.

[Jinoh Kang]

Otherwise, async_waiting() returns 0, leading the socket object to
believe that the previous async request has not yet been acknowledged.
This results in I/O hang for subsequent reads (until shutdown).

Also, async_destroy() calls async_reselect() only after removing the
async request from the queue.  Make async_set_result() consistent with
this behaviour.

[PATCH v2 2/2] server: Reselect only after dequeueing async request.

[Marvin]

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=104817

Your paranoid android.
