For all you know PAD is itself a permanent allocation.  Data space created
with ALLOT can always be un-ALLOTed after the program is run.

If a program is to be portable and run on as many systems and as possible,
with as few dependencies as possible, and what's in CORE suffices or is
in fact better - is that not "best practice" ?
