If you're using imap-uw, this is because the IMAP server from UW is horribly
inefficient with large mailboxes.  Even for a mailbox listing, it creates
temporary storage for all that scanning, and can even copy the entire
mailbox to /tmp and back again for some IMAP commands.

It also has a problem with memory chewing.  It reads in a whole lot of data
for `caching' ... but that end up making the processes 30MB or more in size
for very large mailboxes.
