Umm...actually you *can't* look up LFS inodes by block number, since files
move around the disk as time passes.

It does ... but the cost of the "extra" lookup code that LFS needs is
something like 250 bytes.

(In fact the lfs code can share most of the ufs functions --- which looks
cleaner but at a cost of another 130 or so bytes.  There's a way around
this that I've been neglecting...I'll post it in proposal form shortly.)

That doesn't leave much room :^)
