Hmmm. Note to self: add this to startup on the master backend, in such a way it 
runs before the backend starts. The master backend machine currently stays up 
forever, unless there's a power outage. Although I run a script containing this 
around 02:00 every night, I hadn't considered possible corruption after a power 
cut/restart. Filesystems get checked on startup, why not databases?

In fact, does Mysql do anything useful on startup in this regard?
