Thanks Vibhu!  However, although related, I don't see how your answer
answered my question.  (Or, perhaps it does but I don't get it.)

I'm not really asking about how Java threads work or the fact that all Java
programs (including ABCL) work with threads (although they may not be
thread-safe).  I already understand that.

I'm asking:

A. If I can accomplish what I desire using the regular Java and ABCL APIs.

B. How?

Thanks!

Blake
