IIRC, it's a Multics concept, that Brian and Dennis presumably took south to NJ
with them; if it was original with Multics or is even older I'd have to check
with the retired Multicians list or a archeobibliography.

So the key questions for brian d foy are, where are you staying and would you
like to get further afield or stay close to base?
If bdf's non-mobile but would like to explore, perhaps a mobile monger can
share him a camel ride.

Hey all. For those of you who were at the monger meeting,
I plugged my sci-fi book "Hunger Pangs" and said a new
edition was coming out this week. Well, it's out as

is licensed CreativeCommons-NonCommercial) and buy the
book if you like hard sf

I think there may be a more restrictive limit, at least on Windows.
The OS must be able to find a contiguous block
of virtual memory, i.e. in pagefile.sys.
The paging file may not be able to grow, (depending on
how it is configured) and there may not be a large enough block.
