Review request for qpid, Andrew Stitcher and Gordon Sim.


Incorporated Andrew's suggested changes.

Repository: qpid


The duration calculation in sys/posix/AsyncIO.cpp readable() was happening before the readCallback()
call. This was allowing the loop to execute for more than the allowable time (as set by threadMaxIoTimeNs).

This patch just changes where the duration is calculated in readable() and writeable().

Ran reproducer for https://bugzilla.redhat.com/show_bug.cgi?id=977869. The connection delay
dropped by 19%.
