Inert? This is Smalltalk ;).

Neither of them have any bearing, specifically, on Seaside.  However, they
are both objects whose job it is to hang onto old state - if you're trying
to get rid of garbage, it's a good idea to flush them.  For example:

- Changesets hang onto methods.  Methods hang on to literals.  Literals
can be globals.  Globals can point to anything.
- Command history hangs onto window movements.  Windows can be inspectors.
Inspectors can point to anything.
