Andrew Stitcher created DISPATCH-2298:
-----------------------------------------
Summary: Eliminate some unnecessary uses of pn_proactor_set_timeout
Key: DISPATCH-2298
URL: https://issues.apache.org/jira/browse/DISPATCH-2298
Project: Qpid Dispatch
Issue Type: Improvement
Reporter: Andrew Stitcher
Currently qp_timer_schedule() always calls qd_server_timeout() to wake up the
timer callback handler even if the handler is already running. This causes
unnecessary system calls in pn_proactor_set_timeout(). If the qp_timer_visit()
loop is already running then we are guaranteed that the newly scheduled timer
will be noticed by the loop without having to wake the loop up.
