Suspends the current task until all running tasks in the pool have
finished executing.
Because of terminationHook implementation details, by the time caller
task gets resumed, there will still be one (last) non-recycled running
task in the pool, suspended right before actual termination. Once caller
task gets suspended again for any reason, that last task will be
recycled too. It is possible to manually call
theScheduler.processEvents() after awaitRunningTasks() to force
recycling of that last task at cost of a small additional delay in
resuming the caller.
Note: it is important to ensure that the current task (i.e. the one to
be suspended) is not itself a task from the pool. If that were allowed,
the current task would never get resumed, and this function would never
return.
