For the record, up to this point I am in full agreement with Mr.
Bernstein. We differ in opinion on details, namely how to control
the total amount of memory that a process can grab in this manner.

And, I suppose, we differ in opinion on a couple other things too.
But none of the differences is worth discussion.
