That's implementation depedent between drivers, cards, and pcaps. Peg
tcpdump-workers at ...4097... when you want to help find out.  Not a lot
is typically done at pcap though there are exceptions.

The real answer:

never as much as you would want.  Separating them out might be a fun
project for someone and separating out the stuff that happens before
the InterfaceThread from the things that happen in the pcap_loop
callback and comparing.

A watched process never cores.
