Comment (by ptone):
Yes - the global signal killer context manager is a bad idea - I was
thinking of the narrow context of limiting test interactions - where it
could be useful - but would be a bad choice for public API.
My only hangup on .values().delete() is that I think of values returning
data - not objects, so should be decoupled (conceptually) from the DB -
and so delete seems to leak back to the DB. That is a statement of my
conceptual consistency issue - not that it wouldn't be a clean way to
implement it on the internals side.
Basically trying to muck with signals enable/disable in any public API is
sticky business. I still think a bulk_delete with lots of warning in the
docs is the simplest way forward - if there is a good way forward at all.
