Another option might be to check the thread count is greater than
1 and only lock if it is.  Tango has a routine called thread_needLock
for this purpose, though it goes a bit farther and is true once a
thread has been created through program termination.  This avoids
problems with the situation where you have multiple threads running
and all but one terminate but memory is not yet synchronized.
