Comment (by nickm):

 I've tweaked the heartbeat message to track total downloads by purpose.
 For example, here's a preliminary result for experiment 1:
 {{{
 Dec 12 13:57:22.000 [notice] Heartbeat: Tor's uptime is 1:10 hours, with 5
 circuits open. I've sent 982 kB and received 9.22 MB.
 Dec 12 13:57:22.000 [notice] While bootstrapping, fetched this many bytes:
 Dec 12 13:57:22.000 [notice]     7725566 (server descriptor fetch)
 Dec 12 13:57:22.000 [notice]     445783 (consensus network-status fetch)
 Dec 12 13:57:22.000 [notice]     13266 (authority cert fetch)
 Dec 12 13:57:22.000 [notice] While not bootsrapping, fetched this many
 bytes:
 Dec 12 13:57:22.000 [notice]     518089 (server descriptor fetch)
 Dec 12 13:57:22.000 [notice]     40155 (consensus network-status fetch)
 }}}

 Please let me know if there is more info you think we need or more
 experiments I should try.

 This code needs cleanup before it could go into master.
