[issue21878] wsgi.simple_server's wsgi.input read/readline waits forever in certain circumstances

Just encountered this issue as well.

It's not related to newlines, but to not supporting HTTP or persistent connections (the wsgi.input is the socket's I/O directly, and if the client serves a persistent connection, then the .read() will block forever).

A simple solution is to use a saner wsgi server (gevent works nicely).
Here is their implmentation of the socket I/O wrapper class (Input), and it's read/readlines functions:
