[issue1606] Doc: subprocess wait() may lead to dead lock

[Christian Heimes]

New submission from Christian Heimes:

The subprocess docs need a warning that code like

p = subprocess.Popen(..., stdout=STDOUT)
p.wait()
p.stdout.read()

can block indefinitely if the program fills the stdout buffer. It needs
an example how to do it right but I don't know the best way to solve the
problem.
