New description:

 The summary says it all basically, but note that if `tor` was started with
 `DisableNetwork 0` in `torrc` so the control socket is opened, and then we
 set `DisableNetwork 1` (in `torrc` + send a `SIGHUP`), then the control
 socket is *not* closed. So there's also some inconsistency with this
 option being set at start vs setting it after start, which might help
 debugging this.

 And just to be clear: `ControlPort` TCP listeners work as expected vs
 `DisableNetwork`, AFAICT.

 FWIW, this affets the default `torrc` (+ the default `torrc` of course) in
 Debian with `DisableNetwork 1` added.
