spawn creates the mailbox in the new thread.  I'm going to change thisTid to create a mailbox for the current thread if none exists though.  That should resolve the issue I mentioned earlier.  The main thread gets a mailbox by default, if I remember correctly.  I just didn't want to give other threads one by default because the ref is immediately overwritten by spawn.

I'll try to find some time to give your code a closer look.  It seems like it could be used as a more thorough test suite for the thread and messaging code.
