I'm sorry, but I just discovered something that might be of
importance:

The "expandAllFolders loop" printout actually occurs only 26 times.
Then, "expand" is printed once, and then, "expandAllFolders" repeats
forever.

The figure 26 might not be completely random; these are my mailboxes:

multivac.fatburen.org> lm
INBOX                     INBOX.freebsd             INBOX.other               
INBOX.admin               INBOX.freebsd-doc         INBOX.pinball             
INBOX.binutils            INBOX.freebsd-java        INBOX.sent-mail           
INBOX.blackout            INBOX.gnokii              INBOX.sent-mail.1999      
INBOX.bugtraq             INBOX.internetanslutning  INBOX.sent-mail.2000      
INBOX.cipherchallenge     INBOX.juggling            INBOX.sent-mail.2001      
INBOX.cipherpostmortem    INBOX.junk                INBOX.sent-mail.2002      
INBOX.codebook            INBOX.nada                INBOX.sent-news           
INBOX.cvs                 INBOX.nnimap              INBOX.swox                
INBOX.devildoll           INBOX.nokia               INBOX.xonx                
INBOX.fatburen            INBOX.orc                 

One can notice that the 26th mailbox in alphabetical order is
`INBOX.sent-mail.1999': the first mailbox with a sub-mailbox.

Thanks again,
