In a subshell, I think $$ is the pid of the parent shell, while BASHPID
is the real pid of the current subshell. Test cases:
$ echo $$
24996
$ ( echo $$ )
24996
$ echo ${BASHPID}
24996
$ ( echo ${BASHPID} )
25006
However, multiprocessing.eclass does not appear to do anything with the
pid anyway. Inside multijob_finish_one it reads the pid from the pipe
and does nothing with it.
