It's no longer necessary, since connection attempts are no longer truly
blocking. When CTRL+C is hit in the top-level process, broker will begin
shutdown, which will cancel all pending connection attempts, causing
pool threads to wake. The pool can't block during shutdown anymore.

"self.initialized = False" slipped in a few days ago, on second thoughts
that flag is not needed at all, by simply rearranging ClassicWorkerModel
to have a regular constructor.
This hierarchy is still squishy, it needs more love. Remaining
MuxProcess class attributes should eliminated.

While catching every possible case where "open file limit exceeded" is
not possible, we can at least increase the soft limit to the available
hard limit without any user effort.
Do this in Ansible top-level process, even though we probably only need
it in the MuxProcess. It seems there is no reason this could hurt
