soat with --target never ends?

I've been running

bwauth     679 10.8  2.6 302752 157672 pts/43  Sl   Sep30 1443:58 /usr/bin/python ./soat.py --http --target http://www.torproject.org/index.html

for the past week and a half.

I just checked its logs, and it's got things like

WARN[Sun Oct 10 04:25:39 2010]:A SOCKS5 error 2 occured for http://www.torproject.org/index.html: (2, 'connection not allowed by ruleset')

Sure enough, the Tor log agrees:

Oct 10 04:26:29.306 [info] connection_ap_handshake_send_begin(): Sending relay cell 0 to begin stream 48972.
Oct 10 04:26:29.306 [info] connection_ap_handshake_send_begin(): Address/port sent, ap socket 11, n_circ_id 38707

Does soat not know to exit when it's done with its scans?
