	I am trying to control "DANGER: out of swap space"
by setting the maximum process size.  I have an 11/750 with
1 meg core, and have lowered MAXMEM to 500. (It was defined as
(16*128) in params.h)  Now, I have 6000 blocks on my swap device,
and if I set MAXMEM to 500 (512 byte clicks), a process should
be able to use only 500*512 bytes of core, and thus should always
fit on the swap device, right ?  (I'm testing with just myself, init,
the swapper, and one or two system daemons running).   I'm making it
hang by deliberately starting infinite recursions.

	Needless to say, I still hang with the infamous "out of swap"
message.  My questions are:

	1.  Is there any way to control this kind of problem
on Sys5.2, and why doesn't my approach work ?

	2.  What, if any, is the correct approach.  Does MAXMEM have
anything to do with the problem at all ?
