Uhhhm. Why are we changing this? IMHO passing 0 should work and I don't
see what the actual breakage is.

I'm fine with the patch. I just don't understand why we need it. :/

Here's a small readability suggestion:

lines = ''
while True:
    line = self._body_instream.readline()
    if not line:
        break
    lines += line

I think assigning assigning an unused value can lead to confusions and
the head-controlled loop obfuscates whats actually going on.

Cheers,
Christian
