Comment(by Mark Buechler <Mark.Buechler at gmail.com>):

 In tracing this bt through, I'm a bit concerned that KickDatabase() is
 being called at all since my database, being on the same host, is never at
 any point unavailable. I suspect there's some sort of timeout involved
 here and it only seems to happen during heady EIT processing.

 The issue seems to have gotten a lot worse with the addition of frequent
 checks to QSqlDatabase::hostName() in libmyth/mythdbcon.cpp. I'm attaching
 a patch which keeps the params necessary for QSqlDatabase all local so
 that the only place calling QSqlDatabase::hostName() is in MSqlQuery and
 only once. The MSqlDatabase class now gets its parameters from
 gContext::GetDatabaseParams() and stores & uses them locally.

 Patch attached.
