It's a bit hacky, but you could symlink tail to something nice an
unique, then use the recording finished event or a user job to pkill
your nice unique proces name, eg:-
ian at pvr:~$ ln -s /usr/bin/tail niceandunique
ian at pvr:~$ ./niceandunique -f /dev/random > /dev/null &
[1] 14656
ian at pvr:~$ pkill niceandunique
[1]+ Terminated ./niceandunique -f /dev/random > /dev/null
ian at pvr:~$
As I said, hacky, but it may work?
