That much you can do already.

    TRAPCHLD() {
       while (( ${#jobstates} < MAXPARALLEL ))
       do the background task &
       done
    }

(Of course you need some sort of other loop-ending condition, but you
get the idea.)

You don't really even need the trap for this, your original loop will
work fine as long as you examine ${(k)jobstates} as the list of PIDs
instead of trying to maintain your own array.
