I think ENOSPC is a really bad idea in this case, but I also think we
should make sure Linux filesystems behave unfiformly.

Jeff, can you write a summary of the errors returned by all common
filesystems and post it to -fsdevel for comment?  We should have a
common error for this, and I'd be a happier man if it weren't ENOSPC,
but that's secondary.
