Comment:

 This is a part of containerization. Of the items in this list, we
 presently have parts 1-3 working in our prototype security service,
 Rainbow.

 Caveat 1: finalization needs to be more robust in the face of reboots,
 low-memory, etc.

 Caveat 2: there are some sticky issues involving the interaction between
 filesystems, mount-points, hardlinks, and VServer security context (xid)
 file-tagging that we're presently working out. Rainbow and the Datastore
 are going to have to start cooperating soon (post Trial-2) in order to get
 this right.

 Part 4 (size limits) is being put off for the moment while we work on
 implementing other capabilities.

 Why do you think that deleting the oldest file is the right default?
