> 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.
