I don't think the profile engine is the problem.  VVM continues to run a
bit after I get this message.  The reports from others seem to indicate
that even with this, the app should continue to run.

Nonetheless, for my issue, I needed profiling quick, so I got a free
trial for YourKit.  It worked to help my identify my leak.

I went through the code looking for a System.exit(2), but I couldn't
find one.  I'm really perplexed why this would yield a result code of 2
and otherwise be silent (i.e., the VM isn't dying on an Error).  I
wonder if this exit is coming from the JVM itself.
