Comment (by akaariai):
API proposal for bulk_delete():
1. Does not send signals.
2. Does "fast-path" deletion like in normal deletion where possible.
3. [maybe] If cascades are needed, then cascading is implemented by
fetching just the needed values from the DB, not as objects but as raw
values.
The problem is that no. 3 above seems to be somewhat messy to implement.
So, maybe just error out if cascades are needed instead?
