 Two identical, trivial buildbot master configurations.  One uses mysql and
 the other uses the default database.  They both use the same buildslave
 instance.  They both run on the same Ubuntu 12.04 VM.  I can only run one
 of these two buildbot masters at a time.

 Both "work".  However, during startup, the one that uses mysql shuts down
 PBServerFactory on 9989 for no apparent reason, and the build slave can
 never connect.  The other one, identical in every respect except it uses
 the default database, never has this problem.

 This failure in the mysql-using bot configuration is intermittent: 1 time
 out of 3, the PBServerFactory does not shut down prematurely during
 startup, and the build slave does connect, and everything works as usual
 from then on.

 On one occasion as I watched twistd.log during startup, the build slave
 connected, and THEN the PBServerFactory on 9989 shut down.  Seeing that, I
 restarted the build slave- and it was unable to re-connect.

 Note: this buildbot master configuration is essentially the same one
 presented in ticket #2387. It uses gerritchangesource.

 Some log files are attached.
