The problem we have found would probably only affect the superblock.
Delalloc buffer heads have bh->b_blocknr==0, (since no disk block has
yet been assigned) but we were incorrectly clearing the delay flag at
one point after the filesystem shutdown, and so all delalloc buffers
were lining up to clobber block zero...
I'll check in a fix for this shortly.
