$BASHPID is not working with subshells prior to Bash v4.

  $BASHPID and $! are two different things.

    I need to know the PID of the subshell, inside the subshell. $BASHPID was introduced to hold this value. While $$ still contains the PID of the parent process and $! is not available inside the subshell after all.
