From 1119a2c71a5f6b4e23ac0a19784705002ca9cefd Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Wed, 20 Apr 2011 03:30:03 +0000
Subject: Move disconnect_all to CommonInterface and implement in clients.
 Factor out process thread implementation of Disconnect into Disconnect::Impl.
 Implement DisconnectAll in terms of DisconnectImpl rather than abusing
 Disconnect. Dramatically reduce notification communication overhead of
 DisconnectAll.
