Ah, I understand now.  Unfortunately, it's not quite a perfect
interface like that... rm(1) doesn't free blocks on the loopback...

So, it's probably useful to provide this, but most users will
be too scared, IMHO.  Is it possible to get yourself out of
this mess?  I guess you can always move the files back, delete
the loopback, and create again...
What if the loopbacked fs fails to allocate metadata blocks?
It would be nice to hack some way of the fs thinking it's
full... have a daemon updating the reserved block count (UGLY!)

Any ideas?
