No need for a patch, you can just set a style to run whatever ps
command you like to generate the matches, i use:
zstyle ':completion:*:processes' command 'ps ax -o
user,pid,nice,%cpu,%mem,vsz,rss,tname,stat,start,time,command
--sort=-%cpu'

These are also possible
zstyle ':completion:*:processes' command 'ps aux'
zstyle ':completion:*:processes' command 'ps --forest -A -o pid,user,cmd'
