Ugh.  Yeah, there was a pesky race condition bug in the last iteration of the engine.

The good news is it’s gone, and 0.6.2 will have the fix.    For those who are interested, I’d threaded some operations and, well, that got overcomplicated.   Wrote a handler and am now doing everything single-threaded via the message queue.

Hopefully I’ll release tomorrow if my testers and I don’t find any problems.
