I know.  And that reduced the frequency of the re-write somewhat, but it 
doesn't change it fundamentally.  Removing a message from a folder 
eventually requires that the entire folder data file be re-written, and 
that is usually when mbox files become corrupt.  If the index is 
damaged, it'll become corrupt.  If the operation is interrupted, it may 
become corrupt.  mbox is a fairly fragile format, and one the scales 
very poorly.
