> This is an enhancement request to improve the support to keep connections alive, and re-use them effectively without letting them timeout unnecessarily
> The problem can be described against v4.1.1 as follows:
> 1. We establish an outgoing connection and set the socket timeout to 5 seconds (Time = t0 )
> 2. After receiving the response, we want to keep the socket open for reuse for 30 seconds, and we update the timeout (Time = t1)
> 3. After 6 seconds since #2 above, we get an opportunity to reuse this connection, and again we set the socket timeout to 5 seconds
> 4. Almost immediately, the BaseIOReactor timeout check most definitely notices that the time the socket was last used (t1) is over 5 seconds from the current time, and times out the socket
