OK, I'm happy to try that, but see below.

Seriously?  It only takes a fraction of a second to copy 1.6M on this
machine.  When I look at the status line and see

          imap read: 774K

with the numbers spinning upwards at a rate of only about 15K per
second I grow highly doubtful that it's doing anything other than
reading data from my IMAP server.

If you still want me to profile something, just say the word.
