I don't know much about how larch is going to use this,
but it is certainly the way to go for splash stuff.

Long time ago when I did some work on splash-related stuff
I had a splash branch that added a couple of new stat_* calls
in some extra places (similar to where Thomas' run_hooks are).
These stat_* calls were supposed to be dummy functions
in rc.d/functions and redefined in functions.d/*
which was kind of ugly.

Thomas' proposal looks like a more correct way IMO.
