Correct.

Verify does indeed still fail after adding those 2 files.

However, cloning it succeeds! And it even updated the directory contents 
to the tip revision!

C:\ibi>hg clone recovery recovery_clone
requesting all changes
adding changesets
adding manifests
adding file changes
added 2725 changesets with 27089 changes to 18032 files (+10 heads)
pull obsolescence markers
17 obsolescence markers added
updating to branch default
11528 files updated, 0 files merged, 0 files removed, 0 files unresolved

C:\ibi>cd recovery_clone

C:\ibi\recovery_clone>hg verify
checking changesets
checking manifests
crosschecking files in changesets and manifests
checking files
18032 files, 2725 changesets, 27089 total revisions

So it looks like I could at least use this to get me a working clone to 
move to production. Thanks!

I don't suppose it would be safe to copy such a clone's fncache to our 
master repo?
