This change affects only the behaviour when waiting for children at
restart and shutdown, not "cleanups" in general.  In those cases, yes,
children which ignore SIGTERM will now get SIGKILLed after 8 seconds
rather than the 20 minutes or whatever the previous borked algorithm
did; that is the bug being fixed here.  (This is still slower than 1.3's
~6 seconds till SIGKILL.)
