I wrote a library that can be loaded in userspace that does this.  It's not
very polished, but it works for me.  I use it for rsync when I want files
"deleted" but not from the filesystem.  It creates a .deleted directory in
the $PWD.

If you're interested, I can send it to you.  I have it working on i386 and
amd64.
