python: add a failed test to show Popen deadlock
`Popen.wait()` will deadlock when using stdout=PIPE and/or stderr=PIPE and the
child process generates large output to a pipe such that it blocks waiting for
the OS pipe buffer to accept more data. Use communicate() to avoid that.
This patch is commited to show the issue, a fix patch will come later.
