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() ).
