Sending data from Perl to Python
===

I asked another question about speeding up the process of testing Android with Perl and Monkeyrunner (Jython) and got the following answer: http://stackoverflow.com/a/10859055/1016937.  

Starting a Monkerunner (Jython) script, getting an object once and then waiting in cycle for the data to come from a Perl script (processing it when it comes) seems a great idea. But I don't know how to setup some sort of IPC between Perl and Jython (Python). How can I do it?
