hosed vtest machines

[Poul-Henning Kamp]

Those of you running VTEST machines probably have a bunch of
varnishtop, hist and stat processes eating up CPU.

Please kill them in whatever covenient way you prefer.

I found one bug causing it, but more may appear now that I have
started testing curses mode of these programs in varnishtest.
