I was excited for a moment when I thought the IMAP server could do it
for me.  IMAPv4 has a THREAD command::
http://www.networksorcery.com/enp/rfc/rfc5256.txt (based on
http://www.jwz.org/doc/threading.html)

Unfortunately, it seems this command needs a search criterion; it then
threads the messages that are matched.  I could make the criterion
empty—which essentially asks it to thread the whole "history"
mailbox—and then just pick out the subset I'm interested in, but given
the size of my history I think that'll be prohibitive.

So close, and yet...
