In this specific case, the example terminates when the specified
number of timeouts have been received and processed. There is no need
to pause the scheduler and drain any prescheduled buffers because when
the remain counter reaches zero, all threads are done and should
terminate.
This is a timer example, not a scheduler example. For a scheduler
example, we should demonstrate the proper usage of
odp_scheduler_pause() and resume.
