Re: [Python-Dev] stdlib socket usage and "keepalive"

About controversial... keepalive are usually sent only when the connection is 100% idle for a while, when "while" can be >15 minutes, so the load should be "none" for regular connections.

I guess the concern would be that the keepalive probe itself is subject to uncertain delays, so how long do you wait for a reply before deciding that the connection is dead? If you don't wait long enough, you could end up killing a connection that would have come back if you had waited longer. -- Greg
