> On a sudden stop of the broker it's possible for the KahaDB index to become
> corrupt and the broker will refuse to start. The issue is in the PageFile
> code that is mixing writes to both the recovery file and the index file. The
> writes need to happen in a deterministic way such that the recovery file
> isn't missing data that might make it into the the main index file.
