The heuristic is too fragile and timing dependant.
- As for the initial TLS negociation, wait for the result of the
renegociation request before sending the next one.
- Remove the result ratio calculation and message as we now reach the
timeout in case of exponential backoff or connection hang.
This commit depend on the fix of the timeout, broken by the zombi fix.
The zombi fix did too much modifications breaking the global time-out
function.
As the wait $pid failed, we no longer create the watchdog file.
Fix by reverting unnecessary changes.
