Well, an increase from 0.1 seconds to 0.2 seconds on "polling" in each
thread whether or not the connection should become active doesn't seem like
a big deal.

And there's also some point where it is pointless to accept more
connections, and where maybe remedies like accepting known good IPs,
blocking IPs / IP blocks with more than 3 connections etc. should be
considered.

I think I'll be getting closer than most applications to an eventual
ceiling for what Python can handle of threads, and that's interesting and
could be beneficial for Python as well.
