I can confirm this bug - my private inbox has about 10k messages in it
(starting in 1996, when I installed Linux first on my PC).  I've a quad-core
2.5GHz Phenom with 4GB RAM (so not something slow), and it takes 20 seconds to
thread this inbox.  It takes 10 seconds to thread another inbox with about 5k
messages (that's the collected mails for a single project at work), so the time
it takes is linear.  I think this is unbelievable slow, 5 million cycles per
mail to thread.

Kmail is sort of usable with the tabs - I've now opened up all my big mailboxes
in a tab, and switch between them.  But I agree that this is a severe
regression.
