Well, let's figure out what actually broke, and why.   The vast majority of
files are not appended to after they are first written, I suspect the migration
story still works.   And this issue with over-aggressive estimation for space
needed for indirect blocks is probably something recent in 2.6.33, and I think
we can fix it --- and even if it isn't, I'd really like to know what
applications are checking statfs and aborting as a result, and under what
situations this is happening.
