>Description:
	tvtwm has a really broken vroot model. Although coders historically
	have used a vroot.h to get around it, some applications (xv, and 
	xlockmore notably) just can't do it right.

	xlockmore provides a configure option --disable-vroot which
	'dtrt' when you use tvtwm.
	
>How-To-Repeat:
	run tvtwm.
	compile/install xlockmore
	run with two heads. xlock doesn't blank screen, mouse
	still moves, but until p/w is typed, kb is locked. no
	prompt screen, no message. its a real denyal-of-service
	threat!
	
>Fix:
	This patch to Makefile.common should do it, at the cost
	of a new option in mk.conf.
