APPC, ASCH, and all of those TCP/IP daemons. If it requires a CANCEL to
bring down, it's broken.

It's not like IBM doesn't have lots of code lying around to handle STOP, so
it can't be that much of a resource commitment. The problem is that, on a
platform whose strong suit is reliability and maintainability, having to
issue a command usually reserved for terminating problematical programs to
bring down the system "normally" is an exposure. How do you explain to an
operator that some things can and should be ended via CANCEL, while others
need STOP and using CANCEL on them is a bad thing, while still others will
just plain reject a CANCEL?
