Comment (by sisbell):

 I've been unable to reproduce a tor process not getting cleaned up

 We can detect multiple processes running by running


 {{{
 adb shell ps -ef | grep libTor
 }}}

 This will display something like

 {{{
 u0_a236      26768     1 95 07:53:19 ?    00:00:20 libTor.so -f
 /data/user/0/org.torproject.torbrowser_alpha/app_torservice/torrc
 __OwningControllerProcess 26167
 }}}

 If there are two entries, then its not cleaning up.

 The reason I suspect two processes are running on some devices is that a
 tor process will create a lock on some files while in use. A second tor
 process will block, unable to modify the file.

 I think it will be easier to proceed with debugging a Java version where
 there is easily reproducible and test out the fix.
