"EM is reading from the socket as fast as possible and queuing outgoing responses, but the network is actually unable to deliver those responses at the same rate. This causes the internal outbound buffers to grow, thus increasing memory usage."

This is a potential DoS attack.

The proposal is reported in EM tracker: https://github.com/eventmachine/eventmachine/issues/160
And the original issue is also reported there: https://github.com/eventmachine/eventmachine/issues/157

PS: No milestone asigned to this issue as maybe it better to leave it for later than 1.1.0.
