{{Quickfixn}} How do I force-disconnect FIX?

[Grant Birchmeier]

This is an open issue.
https://github.com/connamara/quickfixn/issues/45

We appear to have a number of Initiator.Stop()-related issues.

It looks like we are about to get a little outside help with QF/n
development, so hopefully we'll get some forward-movement on this project
again.
