Slow websocket consumer problem

[majek]

SockJS-erlang fails on slow websocket consumer.

For example:

To reproduce pip install websocket-client and:

from websocket import create_connection
ws = create_connection("ws://localhost:8081/amplify/0/0/websocket")

result =  ws.recv()
print "Received '%s'" % result


for i in range(10000):
    ws.send('["18"]')


#    ws.send('["18"]')
result =  ws.recv()
