I've looked through the code fairly extensively for signal handling
behavior.  I was only asking about that sample and did not intend to
imply that VMS never used SIGINT.  I'm aware of the different SIGINT
handling under VMS, and have dealt with it in what seems like a workable
manner.

You are right that I had missed the exit() macro.  I see that it
disables a lot of signals, but only if LYOutOfMemory.  Again, I'd like
to ask you about the rationale for this (the code says FM all over it).
More to the point: I understand why you might want to ignore signals
during shutdown.  But then why do you re-enable some (but not all) part
way through?
