Programs that method an object shouldn't method anyone else's objects. If
an author did this, then he would be wrong. If it turns out that DPaint *does*
need the space, it should tell the user that there's not enough memory, and
ask if he would like to toss his work session.

Not to mention that he gets to hook up the Butcher icon to the dPaint icon
in his IPC Patch Panel... which gives a great visual feedback. I must admit
that one reason that I prefer PPIPC over OOIPC (apart from the fact that
PP > OO :->) is that I *want* to wire my software up like this.

No, it should be started as soon as possible. I think Stuart should get
down to writing code so we can have some facts. It's so much more satisfying
to flame when you have some real facts.
