[ Thanks for everyone's comments! ]

Keep in mind that btrfs was released and ran for a long time while
intentionally crashing when we ran out of space.   This was a really
important part of our development because we attracted a huge number of
contributors, and some very brave users.

For fsck, even the stuff I have here does have a way to go before it is
at the level of an e2fsck or xfs_repair.  But I do want to make sure
that I'm surprised by any bugs before I send it out, and that's just not
the case today.  The release has been delayed because I've alternated
between a few different ways of repairing, and because I got distracted
by some important features in the kernel.

That's how software goes sometimes, and I'll take the criticism because
it hasn't gone as well as it should have.  But, I can't stress enough how
much I appreciate everyone's contributions and interest in btrfs.
