Thank you for the explanation, Alain!  This is helpful.  (I just now
saw your reply, sorry.  For some reason I didn't get a daily digest
after my posting.)

I will try your code changes to reduce the memory consumption from this.

Okay, this makes sense.

However, for some applications, I'd like to make one forward pass
through the mailbox, message by message, and I don't need to back up. 
I would get what I need from each message, then call the 'next
message' method of the iterator.  I'd be willing to accept that I lose
the caching that is normally done.

It's similar to a SAX style of parsing for XML.

I'd be happy to test our your new code whenever it is ready.
