This comes from trying to fix the annoying recurring problem with
mistypes in KDE which has been going on since at least December.
First, we add the attempt to kind of 'precache' the kicker menu
in aasetting.pm. Then, I thought, all this snapshot loading has
to be putting a lot of load on the workers. And when each subtest
passes, it shouldn't really be necessary - they all end with
quit_with_shortcut(), which verifies that the app exited and we
got back to a blank desktop, so successful subtests should not
usually interfere with each other. We probably only want to
rollback on *failed* subtests, which is in fact openQA's default
behavior. There only seems to be one case where a test changes the
system state such that later tests might be affected, so I kept
always_rollback just for that one. I've run this through three
cycles on GNOME and KDE and it looks good.
