Losing data is always bad - that's why it's in a database, not a filesystem.
But these systems have been pretty reliable and are on UPS, etc. This
is a created table, so it's not life critical ... but it is expensive.

Yup. Not nearly big enough - index is 15GB!
And the code seems to misbehave, leading to crashes, at the limit.

We "need" INSERT IGNORE, so this isn't really an option for us,
unfortunately.

I'm going to mount them as ext2fs for the time being.
