Hi Andres (and sorry for the typo in your name earlier in the thread) --

> ...And probably a good idea to cc the author if so.

No offense intended, I certainly intended for you to be not just on
the "Cc" list but on the "To" list of the new thread, but you are too
quick for me and, due to time constraints, I may not get to that
new thread until next week (it's a holiday week in the US).  But until
then... a quick clarification:

I meant "ever be necessary in the dynamic memory (e.g. tmem) paradigm",
not the squeezed (or MS -memory-balancing-engine) paradigm, where I can
at least fathom it.

Feel free to start the new thread if you like, but I may not be able
to answer for a few days.

Happy Thanksgiving-week-in-the-US,
Dan
