Hmmm. I don't think running tdb_traverse is the best way to
figure if a tdb is corrupted or not. I've for example seen
tdb's with cycles in the freelist, ending up in 100% CPU for
everyone trying to add something to it. This is not covered.

I'd hesitate to add this to the main tree, as I think it's
really unreliable, and I don't want to give the illusion we
really check something.

However, having a decent consistency checker for tdb's would
be great, but this will probably involve a lot more work.
