The most logical source of cause, as David points out, is the Python script 
since that's the factory which actually enables the error. I, foolishly, 
looked at another direction.

The cause was that the Python script read the pipes sequentally, first stdout 
and then stderr(which is a bad approach, yes). Mostly stdout closed before 
stderr required a read; in the cases it didn't, it blocked, naturally..
