I'm not talking about poorly-behaved or malicious programs.  I'm talking
about perfectly ordinary things like SENDFILE EXEC using Diag(8, 'CLOSE
PUN') to capture the file sent message.  That was the very first thing I
tried to check out PIPESERV's reader handling, and PIPESERV never saw the
file arrive.  A program can be as polite as you want in saving and
restoring the IMSG setting after issuing some command quietly, but it
can't give back file arrival messages that go to the console while it's
running.

None of this is going to happen in Bob's super-simple server as he
describes the requirements today, since it'll just be issuing a bunch of
TRANSFER and SMSG commands.  His other concern of having to process too
many additional IMSGs shouldn't be a problem, either, since only the
TRANSFER commands would generate any, and he'd probably trap then when
issuing them with the CP stage.  But as soon as he has some other little
function to add, he might have to worry about it.
