[tor-relays] stem library: huge difference between resolvers "proc" and others, eg. "netstat"

[Damian Johnson]

Hi Toralf. Unfortunately I don't know offhand, though I'd certainly be
curious if you find the answer. At the end of the day connection
resolvers use the proc contents, so this might be a bug in how I'm
filtering connections in Stem or maybe a bug with its underlying proc
resolver.

Unfortunately I can't troubleshoot this without a local repro. If
you'd care to dig in I'd suggest adjusting the script a little to
print the connections, then see in what way netstat differs from proc.
Is it a strict superset? Does it have duplicates? Anything about the
connections which differ that seem interesting?

Cheers! -Damian
