It should already occur, as it's called directly in bq_sig_hup_handler().

One other thing that's always been on my "itch to scratch" list is to
drop the callback argument from pcap_cache_reload() and just use regular
tevent completion callbacks. It'd currently be pretty messy though, due
to the number of ways that pcap_cache_reload() is called, i.e. the
combination of spoolssd, "smbd: backgroundqueue", etc.
