As I noted in a message a few minutes ago in response to a similar
suggestion, I didn't think of this.  On the other hand, can a Rexx program
receive a "halt" signal when it its own thread of execution is in
a Rexx-callable DLL?  Now that I think more about it, I know from
experience that I can hit Ctrl-Break and that this works in the hung
condition with which I am concerned.  I think you may have given me the
answer; I'll try it.

I don't much care what the Rexx program does when it is forcibly
terminated, althouh I suppose cleaning up would be nice.  I just want it
dead.
