... and powerd should be tought about them ;-) (one way or the other,
see smb's recent comments at tech-kern)

What would hardcoded SIGPWR action in init(8) gain us, compared to
any-action-we-might-want run from powerd script? If it's just latency
issue, the user needs to raise critical capacity (or whatever) treshold
on the battery.

I really don't think signals are the best way to propagate this kind
of system conditions...
