If you are unwilling to tolerate any delays at all when scrolling
through a million message mailbox, where do you want to put the
asynchronicity?

I guess it might be possible to have all the metadata in memory to
populate the tree, but not the message bodies? So whenever you load a
message, that's when the async DB hit happens?

What size of folder do you think we should have performance targets for?
