# The panel is the only way a teacher has of getting anywhere, so it is
# never allowed to stay dead.
#
# Plasma's own unit already restarts plasmashell on a crash, but it gives
# up after three restarts in sixty seconds and the panel is then gone until
# somebody reboots the room. That is measurably the failure a classroom
# machine has already had once, with the old hand-written dock, which had
# no supervision at all.
#
# Measured in the lab: with these four lines, plasmashell survived eight
# consecutive SIGKILLs one second apart and came back every time in about
# 2.4 seconds. Without them it was permanently gone on the third.
