See http://svn.mythtv.org/trac/ticket/7836 for some description of why
this happens.  In short, Qt's mysql driver thinks that whatever thread
opens a database connection will also close it, but this is not
necessarily true in MythTV because of database connection pooling.
Ticket #7836 fixed the annoying 5-second delays that would accompany
this message in the frontend, but it still happens upon exit.

There's some chance that a newer version of Qt would fix this.  It
won't be fixed in MythTV without another patch.  That (hypothetical)
patch would probably isolate all the database connection pooling into
a single thread.
