  If the system is alive enough to panic, but ignoring the world, give
it something to panic about ...
	on a vax (for example):
	^P		! get it's attention
	H		! halt a 780 (ignored on smaller vaxen)
	E/G F		! remember PC for later analysis
	D/G F C0000000	! the beginning of the illegal gigabyte ...
			! -1 is easier to type, but 7[35]0's don't like `-'.
	C		! continue at silly addr

extreme embarrasment produces a nice dump -- buffers are sync'd & whole state
preserved (except for the clobbered pc, which was prob the idle loop anyway).
