Comment(by rransom):

 Replying to [comment:1 chiiph]:
 > So, TAKEOWNERSHIP will be used when the process doesn't have
 OwningControllerPID option set? There may be some conflicts there, or will
 the TAKEOWNERSHIP set OwningControllerPID and fail if the latter is
 already set?

 The TAKEOWNERSHIP command and OwningControllerPID options should do
 exactly what I specified that they should do in the ticket âdescriptionâ.
 There is no conflict between their effects.

 When Vidalia is configured to âownâ the Tor instance it controls, Vidalia
 should specify its process ID to Tor using the OwningControllerPID option,
 and then send the TAKEOWNERSHIP command when it connects to Tor's control
 port.  After Vidalia has sent the TAKEOWNERSHIP command, it should unset
 the OwningControllerPID option so that Tor will stop polling for a process
 with that process ID.

 The reason to have an OwningControllerPID option is to try to avoid
 leaving a zombie Tor process if Vidalia exits before connecting to Tor's
 control port.  The reason to have a TAKEOWNERSHIP command is to reliably
 avoid leaving a zombie Tor process if Vidalia exits after connecting to
 Tor's control port, even if the OS gives a new process the same process ID
 that Vidalia had before Tor polls for it again.
