Trying to use Hooks to stop processes Circus don't stop

[paulocheque]

I am trying to create an workaround for the #986 issue.

But this creates two processes for the same watcher. Ideas?

import os
import subprocess


# hooks.after_spawn = fix_circus.save_pid
def save_pid(watcher, arbiter, hook_name, pid, **kwargs):
    with open('api.pid', 'w') as f:
        f.write(str(pid))
    return True


# hooks.after_stop = fix_circus.force_kill
def force_kill(watcher, arbiter, hook_name, **kwargs):
    with open('api.pid', 'r') as f:
        pid = f.read()
        print('Force killing {} process'.format(pid))
        subprocess.call(['kill', '-KILL', pid])
    os.remove('api.pid')
    return True
