If I run with --mt 1 it runs for a bit....however if I change that to --mt 10 it crashes immediately. Tried this on an old dual-proc and a new quad-core system. Here's the stack from the quad-core:

So, I believe I have the right code. If you want me to perform any further testing/changes just yell.
