Eventlet is a concurrent networking library for Python. A websocket peer
may exhaust memory on Eventlet side by sending very large websocket frames.
Malicious peer may exhaust memory on Eventlet side by sending highly
compressed data frame. A patch in version 0.31.0 restricts websocket frame
to reasonable limits. As a workaround, restricting memory usage via OS
limits would help against overall machine exhaustion, but there is no
workaround to protect Eventlet process.
