Yes; I saw this and use it as a workaround atm.  But:

a) it requires parsing of human readable text

b) there is a race between 'initctl status' and the 'kill' where service
   might vanish and a completely different process is started with the
   same pid

Hence, an atomic 'initctl kill' functionality would be nice.
