If you are unwilling to tolerate any delays at all when scrolling<br />
through a million message mailbox, where do you want to put the<br />
asynchronicity?<br />
<br />
I guess it might be possible to have all the metadata in memory to<br />
populate the tree, but not the message bodies? So whenever you load a<br />
message, that's when the async DB hit happens?<br />
