Ev::resume — Resume previously suspended default event loop
Ev::suspend() and Ev::resume() methods suspend and resume a 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() .
Calling suspend / resume has the side effect of updating the event loop time(see Ev::nowUpdate() ).
