NP.  I track this list looking for trends but don't always build the 
latest whizbang kernel unless I'm fighting with a specific problem.
Using an old kmail, I thought I could improve its performance with shorter 
expiry times on busy lists.  Not as helpful as I'd hoped.  Once a certain 
number of read mails exist, 1.13.5 has to be stopped and restarted 
immediately else it takes several seconds to find the next unread.

Sorry for the noise.

Cheers, Gene Heskett
