Something is seriously wrong with my install, the load goes up to 25 and the mythtv installation loop continues. Eventually there are broadcast messages stating that seemingly random processes are going to be killed:
"Out of memory: kill process 1138 (mysqld) score 32202 or a child"
"Killed process 1138"
Spawn_DCErouter, mediatomb, DCErouter shared the same fate but kept coming back for more.
The strange thing is that the system wasn't out of memory:

I'm going to try a fresh install.
