Just a thought, check that you are root, perhaps you do not have
permissions and kill is silently failing. Also check the state of the
process, I know on QNX the OS does not like to kill HELD (SIGSTOP)
processes and generally requires you SIGCONT them first.
If anything kill -9 should ensure the process never gets another CPU
cycle, it should die the next time it is schedualed to run, if it never
runs then it may not be able to handle the signal, depends exactly on how
linux's priorities end up working.. Check you haven't got a cpu intensive
process running someplace too..
