def fix_ssl_monkeypatching():

"""
|
|
eventlet works by monkey-patching core IO libraries (such as ssl) to be non-blocking. However, there's currently
|
|
a bug: In the normal socket library it may throw a timeout error as a `socket.timeout` exception. However
|
|
eventlet.green.ssl's patch raises an ssl.SSLError('timed out',) instead. redispy handles socket.timeout but not
|
|
ssl.SSLError, so we solve this by monkey patching the monkey patching code to raise the correct exception type
