not really. it was related to the problems with /tmp directories
in linux.
consider a standard unix-style mailbox. if you make the file
append-only, but world writable (not world-readable), anyone
can append a message to your mailbox, but only you can rewrite
it or read it.
the thought is that it would be nice to have a similar capablity
with a directory, where the permission to remove is seperated from
the permission to create.
