Comment 4 for bug 1168154

Importance acknowledged; I believe this will be addressed by lp:1183309 (the gui can just set the force flag by default).

We would in the meantime be able to mitigate the effects somewhat by extending the range of situations in which a unit can be removed directly (any time before its machine agent starts) and can be set directly to Dead (any time before the "start" hook completes successfully), but I'm not sure it's worth the effort vs a proper fix.
