Yeah, I have a feeling this is yet *another* problem with this proposal.

I guess I should go and read the actual patch and moan on l-k if these
problems really do exist. (Still, I'm the last-ditch Viro Defence Force
would spot them if I didn't complain. I'm almost tempted not to moan
because Al's demolition is bound to be so much more amusing than any I
could come up with... ;) )

Right. What we want is secure de-allocation, not secure delete. That looks more like attaching deallocated blocks to a .trash file than linking unreferenced files to a .trash directory.
