s4-python: fixed annoyance where control-C doesn't kill our python scripts

Browse Source 
We want our scripts to die immediately when a user hits
control-C. Otherwise we not only annoy the hell out of the user, we
also risk db corruption as the control-C could get delivered as an
exception which gets mis-interpreted (eg. as a missing db object). We
use transactions for all our databases, so the right thing to do in
all our command line tools is to die immediately.

/* one of the most annoying things about python scripts is
that they don't die when you hit control-C. This fixes that
sillyness. As we do all database operations using
transactions, this is also safe. In fact, not dying
immediately is unsafe as we could end up treating the
control-C exception as a different error and try to modify
as database incorrectly
