This really depends on the undelying storage used.

Packing does two things:
- It removed records for objects that are no longer referenced
(as of the pack time), or, IOW, it doesm garbage collection.
- For storages that support undo (and time travel), it also
removes records that were not current as of the pack time.
Both of these, especially the latter are a little bit similar to
defragmentation or optimization. In addition, the particular storage
implementation may have other issues/tools. For example, if the
Oracle storage is used, them whatever fragmentation or optimization
issues or adminstration tools provided by Oracle apply.

This doesn't really apply.

Currently, the only way to do this is with a non-versioning storage,
such as the Berkely DB storage.
