[Bug 251510] net-mgmt/bandwhich process <UNKNOWN>

--- Comment #3 from Graham Perrin <grahamperrin at gmail.com> ---
It continues to show a single <UNKNOWN> whilst (for example) running Firefox;
and before, during and after a start of Thunderbird. Apparently a single
process with a rising number of connections, as Thunderbird makes its
connections. 

I start Falkon, the number of connections for <UNKNOWN> rises; I quit Falkon,
the number drops. And so on. 

bandwhich aside for a moment,
<https://lists.freebsd.org/pipermail/freebsd-current/2020-November/077655.html>
there's a suggestion to use fstat. 

Elsewhere recently I read stronger discouragement from relying upon lsof on
FreeBSD. Not bookmarked (sorry) but if I do find the technical discussion
again, I'll add something here. Note to self: not found in #freebsd on IRC. 

In the meantime:

I see <https://github.com/imsnif/bandwhich/issues/149#issuecomment-629828150>
but whether fstat is feasible for bandwhich, I have no idea.
