Yikes ... the above performance doesn't seem very scalable.

I'm currently doing Production work with a client and when there's an
`event', I may get an in-rush of several hundred messages in one
shot.  After sorting the messages by Subject, I usually can delete
nearly all of them.

FWIW, I'm currently using Thunderbird although I long for the day when
I can return to Kmail2.

Cheers,
