Is there any way we can determine the progress during all passes?  At
the moment all we're seeing is lines like the following:

(pass1.c:213)  Setting 557096777 to data block

Is this representative of simply the numbers of blocks in the
filesystem?  If so, how do we get the numbers of blocks in the
filesystem while the fsck is running?

We use this FS for backups and we're currently determining whether we'd
be better off just wiping it and re-syncing all our data (which would
take a couple of days, not several) so unless we can get a reliable
indication of how long this will take, we probably won't finish it.
