Keep-alive time just for first signal
We're using wt server in some customers that use networks monitors to check service avalibity, this tools usually ping a server each minute or half a minute to check if the service is alive.
When using "dedicated-process" this means that each ping will generate a new process consuming a considerable amount of memory, this sessions will not be closed until the the defined timeout is reached.
I beleive that after a session is created, if we don't receive a keep alive, lets say, 5 seconds, the process/session should be close directly.
Controlling first keep-alive/timeout in a different way can helps a lot with this kind of services.
