[tor-talk] log heartbeat update on demand?

[Lars Noodén]

At intervals Tor posts some status updates to the system log file:

	Aug 15 19:56:40 relay4 Tor[26018]: Heartbeat: Tor's
	uptime is 6:00 hours, with 10 circuits open. I've sent
	2.11 MB and received 7.18 MB.

I see that Tor takes different actions upon catching various signals
(HUP, USR1, USR2, etc).  But none of these signals force a short,
concise status report like is given in the heartbeat.  How can this
heartbeat update be invoked on demand?
