In the subprocess documentation, I haven't found any hint if the pipes created by PIPE are blocking or non-blocking.
I.e., if I call p.stdout.read(), will it block in certain circumstances? The documentation warns about that. How can I avoid that?
Using p.communicate() is not an option for me because I don't want to block/wait until process has exited.
The only option I see right now is to create another thread and to code some simple non-blocking file-like wrapper object. However, this seems very complicated for such simple task.
