Make persistent timeouts more accurate. Previously, if the user scheduled a persistent timeout for {1,0}, we would schedule the first one at "now+one second", and then when we were about to run its callback, we would schedule it again for one second after that. This would introduce creeping delays to the event that was supposed to run every second. Now, we schedule the event for one second after it was _last scheduled_. To do this, we introduce internal code to add an event at an _absolute_ tv rather than at now+tv. svn:r1520
