The easiest way to do this is to put a limit on the number of threads
that can run at once. You need to keep track of when a thread is started
and stopped. If the next thread to start would go over the limit, block
the caller thread with wait(), or just throw an exception - whichever is
appropriate. Also, the limit should be configurable.
