> When KahaDB processes a KahaUpdateMessageCommand it's possible for the size statistic
to be inadvertently increased in size.  This can happen if the location in the journal of
the message command matches the new location.  This bug won't show up in normal usage as typically
an update message command is only processed when a new command is written to the journal (and
hence a new location) but should still be fixed.
