Need to create subprocess...

[drstoka]

Hello,

I have to run a program as a child process inside my python program and 
redirect it's output through a pipe to a parent program process.
So, I wrote this:

pipe = Popen('example_program', shell=True, bufsize=0, stdout=PIPE).stdout

and it works great.

Now, in parent program I need to wait for a some time and if a child 
(example_program) does not finish in that time, kill the child.

How do I do that? Please help.
