Are you sure you want to kill already-running instances, rather than
simply exiting to let them continue running without interference?

There's some discussion here:

http://mywiki.wooledge.org/ProcessManagement#How_do_I_make_sure_only_one_copy_of_my_script_can_run_at_a_time.3F

But it mostly deals with using locks to detect an already-running instance
so that you can gracefully exit -- not kill the other guy.

Can you tell us what you're actually trying to do?
