> Currently, {{TimeScheduler3}} has a runner thread which continually takes tasks from a {{DelayQueue}} and submits them to the thread pool.
> If a task is non-blocking, this is not necessary; instead the task can be run on the runner's thread. This will reduce the number of thread created in the thread pool.
> Investigate whether it is possible to mark tasks as blocking or non-blocking. Example: an {{AgeOutCache}} task is always non-blocking. A {{UNICAST3}} or {{NAKACK2}} retransmission task is (potentially) blocking if {{TCP}} is used as transport and non-blocking if for example {{UDP}} or {{TCP_NIO2}} are used.
