NPE is thrown from VMConnection

[Robert Field]

I am unable to reproduce this, which isn't surprising because 
synchronization is a very platform dependent area.  I have just pushed a 
fix that should address this.  If you see other cases of this, please, 
again, send a stack trace.

Thanks,
Robert
