		  Swap Problems with the 3B1/UNIX PC
		  ==================================

Well, I've just bought one of the 3B1's on sale, and I am concerned.

I've heard several stories about system problems if there is insufficient
swap space; and now it begins to sound like the mysterious error that
crops up with uucp running is also swap related.
	It sounds like 3B1 UNIX does not properly detect the end of
the swap device; most likely, it detects the out-of-swap-space error,
because it apparently kills processes, but likely has a boundary value
problem and is overrunning the end of some table related to swap.
(That's a bug I've seen in many UNIXes).

Seems to me like there are two things that need to be done: (1) find a
way to increase swap space (I've half a hope of running GNU Emacs on
this machine, and will need much more than the default 2.5M of swap),
and (2) locate the garbage planter on swap errors.

I've not received my machine yet, so am stuck. A friend of mine who was
a longtime 7300 user remembers that an early version of the UNIX
allowed swap size specification. Does anyone have such a disk around,
to disassemble?

[I can't wait to get my machine. Is anybody interested in putting
up a decent UNIX on it?]
