Here are some misc cleanups for async_handler:
- Fix the default number of iterations in async_handler so that the run
duration is really ~1 minute @ 2GHz according to the comment.
On my test box @ 2GHz, it's more like 0.25s for 5000 iterations.
- swap signal_thread() and handler_thread() function names to
better reflect what the functions do.
- remove the call to join_thread(signal_id) as join_threads() does
the job.
