I see that we are asking about two different things: the maximal possible
memory you can request, and the amount you can request without going into
virtual memory. But in either case, we seem to be getting our results by
experimentation -- and getting rough results. It would be much better if
there were a way to directly and exactly get the info we seek.

Thanks for the comments. I wrote the following program to try to get at
the issue. It reports back the level of memory that does not get an "op.
sys. refuses to provide memory" error.
