Thanks, that seems to fix the problem in the test program.  There is 
still a problem in our application that I am investigating.  More on 
that later perhaps.

One question I did have is this:

It seems that it is possible for a thread to be inside of 
natReference.cc holding the Reference's lock when the garbage collector 
stops the thread.  If this were to happen, the garbage collector would 
block forever waiting to obtain the lock when it entered.

Is this possible?
