That makes sense if the timing is ugly


Can this occur

	rhgb X server -> decides to go away
	gdm X server starts
	gdm X server issues switch to screen
	rhgb X server cleanup issues switch back to text mode screen
	gdm X server waits for its screen

Also does this ever occur without selinux ?

VT_ACTIVATE will also return 0 if you try and switch but the current vc
owner says "no". Thats a bit antisocial but seems to because historically
VT_ACTIVATE has been throught out as "request switch"
