kill subprocesses using bash script

Question

I want to run a python program 1000 times. If successful it returns output in about 90 seconds, else continue to run may be for 4 hours. I want to run a bash script that will run the python program in a loop in such a way that it waits 100 seconds for the script to terminate successfully else kill it.

It must not kill the next instance of the program which may become successful.

I am working in Ubuntu 12.04 lts.

for i in {1..1000..1}
do
    ./myprocess.py
    sleep 100
done

#And then what........?

Please help
