I wonder if this is due to changeset 17834
(http://svn.mythtv.org/trac/changeset/17834) which added the
MDBManager::PurgeIdleConnections() function.  This function is run
when a new DB connection is initiated, and "cleans up" items in the DB
connection pool that have been idle for at least 1 hour.  Presumably
some interaction between Myth, QT, and MySQL is causing this.

I can try a few things:

* Disable the PurgeIdleConnections() function.
* Upgrade mysql.
* Upgrade qt.
* Move the PurgeIdleConnections functionality into a separate thread.
