[issue21332] subprocess bufsize=1 docs are misleading

[akira]

akira added the comment:

I've changed test_newlines to work also with Python io implementation.

I've updated the patch.

Note: tests use 10 seconds timeouts: I don't know how long it should take to read back a line from a subprocess so that the timeout would indicate a deadlock.
