Subject: [PATCH] [project @ 2005-04-20 13:58:00 by simonmar] Remove bogus
 code: the mutable list does not need to be rebuilt during
 compaction.  It just needs to be updated, which is already
 happening.

(fixes crashes in compacting collection; I think a different fix is
required for STABLE, though)
