We've proven the point that all memory gets cleaned up. We also see that both threads get to do some work and that both close as expected. <P> It's also worth mentioning that it's just an accident that all of the blocks are created and enqueued before any are processed. Run the test on a multi-processor or with more iterations and you'll see some get processed before all are created. <P><HR WIDTH="100%"> <CENTER>[<A HREF="../online-tutorials.html">Tutorial Index</A>] [<A HREF="page07.html">Continue This Tutorial</A>]</CENTER>
