while using a php client with node.js server, i stumbled upon 100% cpu usage for the client.
To prevent this behavior for idle clients i added idle checks for empty select() calls, empty $readables and empty $client->requests. If $emptySelectCount hits $emptySelectThreshold the $interval is incremented by $intervalStep and the count is reset.
If the loop checks out, not to be idle, the interval is reset. Otherwise the interval is incremented until it hits $intervalMax.
This patch needs review, and still some means of configuration.
