Hmm.. perhaps there is merit in both views.  So why not do both?

HYPERDSK does this sort of thing:

	It traps c/a/d and beeps the first time you press it,
	while it hastily attempts to flush the cache.

	When pressed a second time, after the beep warning,
	c/a/d does what we (users) expect it to do:  it reboots
	MSDOS from scratch.
