Another strategy would be to defer scanning the tree, as we can  
for IMAP folders, and defer loading each mailbox view until the  
mailbox is found. The mailbox view is used to record whether or  
not the mailbox is visible, so the tree could be populated only  
as far as it was expanded in your previous session (actually, one  
level deeper, so we know whether a visible folder has children).
Of course, if you have all 4000 folders visible, that wouldn't  
save you any time...but in that case, probably nothing will!

The deferred scanning part is working quite well now in IMAP  
trees (OK, in mine!).
