The PID of the supervised process will be the same as that of the
'run' script if it is correctly written, so it's $$ for a shell
script, and the value of the environment variable specified to the
getpid program for an execline script.

* http://www.skarnet.org/software/execline/getpid.html

It is not available inside the 'finish' script, but even if it was, it
is no longer useful since, if that script is being executed, the
supervised process has already terminated, and the PID it had has been
'released'.
