Ev::suspend — Suspend the default event loop
Ev::suspend() and Ev::resume() methods suspend and resume the default loop correspondingly.
All timer watchers will be delayed by the time spend between suspend and resume , and all periodic watchers will be rescheduled(that is, they will lose any events that would have occurred while suspended).
After calling Ev::suspend() it is not allowed to call any function on the given loop other than Ev::resume() . Also it is not allowed to call Ev::resume() without a previous call to Ev::suspend() .
