[PATCH 5/5] server: Post socket events only if selecting for them.

This introduces a test failure, reflecting a failure to trigger FD_OOB after two
separate bytes of OOB data are sent. Since two bytes are not actually received,
and since the first is never consumed anyway, I am again inclined to argue that
this makes the test results more accurate rather than less.
