SIGTERM signals GNU Parallel to stop spawning more jobs and wait for
running jobs to complete.

If you send SIGTERM twice GNU Parallel will exit immediately.

If this is not what you want, you most likely need to make a wrapper
that saves $$ to you in a file:

    parallel 'echo $$ > {%};sleep {}'  ::: {90000..90009}

If the reason for getting the pid is to kill run-amok processes,
consider looking at --timeout and --memfree. The both send TERM, TERM,
KILL to child processes.
