Yes, it's to show why it was called.  I'm fine for it to be there, but
it should say "new connection caused by: " so it's clear it's not an
exception.

When doing this on locks I actually wanted a shortened traceback, with
just the consecutive function names on one line.  It's normally
obvious where the call was in the method.
