/*
* This test is aimed at making sure that unref timers queued with
* timers._unrefActive work correctly.
*
* Basically, it queues one timer in the unref queue, and then queues
* it again each time its timeout callback is fired until the callback
* has been called ten times.
*
* At that point, it unenrolls the unref timer so that its timeout callback
* is not fired ever again.
*
* Finally, a ref timeout is used with a delay large enough to make sure that
* all 10 timeouts had the time to expire.
