Thanks, Greg. 
--There seem to be many different parent processes, so that approach
won't work here.
--I didn't grasp the meaning of the -f option because I was thinking
that the whole thing was the command--that's why I tried to put it in
quotes. I gather, thinking about what you wrote, that only 'php' is the
command.
--also, the examples I saw didn't use the -9. 

Thanks again.
