Handle simultaneous subscription to diagnostic messages.
Delay new recurring requests if there are already existing in flight and
cleanup active request to correctly set in_flight_ flag to false else new
request can't be launched as there is always an old one considered running...
Modify a little bit DEBUG message and cleanup useless code.
