The signals which are sent on VT switch are still there, so stuff can
still be executed on VT switch. The question is whether that stuff has
to be executed at a particular time or not. It seems clear that the master
stuff DOES have to be executed at exactly the right time. But what about the
other stuff? In particular, would it matter if the other stuff in the LeaveVT
callback of a frozen server were not executed when switching away from that
server?
