Mathias,

i can trigger this problem on my laptop which is *not* running
mythbackend by simply issuing 'sudo killall -HUP mysqld_safe'. So it's
not related to MythTV.

In fact, if you issue 'mysqladmin refresh' as done by mysqld_safe when
it catches a SIGHUP, mysqld will *not* crash. See Mario's explanation
why the patch is broken.

How to break it:
sudo killall -HUP mysqld_safe

Expected behavior:
* 'mysqladmin refresh' is run
OR
* nothing happens, as intended by upstream

Resulting behavior:
* mysqld is restarted
