Log requests with elaspsed time as INFO level

I picked the log design from existent http servers, I find it useful to be able to see in the logs request that failed and the one that succeeded with the time that they took !

The way I see it is that ReplyChannel is in general hackish :), IMHO a ReplyChannel should only send one reply type and not something like ACK followed by error, which is broken.

If you disagree on adding hackish stuff already hackish code, then it probably better to not do it now, and only when ReplyChannel is fixed.

Thoughts ?
