Implementado com gevent..

Funciona com número pequeno de urls. 

Deve ser implementado o uso de gevent.pool para dividir urls de registro de log ao Ratchet em lotes.

Quando um número grande de urls é preparado para ser disparado para o Ratchet o gevent acaba mantendo várias requisições abertas dando o seguinte erro abaixo:
