Yes.  Plus some restrictions on arguments to the new thread to help prevent data races.

This is my fault.  I suppose I should do something about this for the next release.  Priority messages basically live in a separate message queue.  When receive is called, if the priority queue is non-empty then the receive() pattern is applied to that.  If that receive() call can't handle one of the priority messages an exception is thrown.  So long as the priority queue remains empty, receive() will block until a message arrives that it can handle.  If you want non-blocking behavior then call receiveTimeout() instead.
