The way how the default setting works is not backward compatible. Say 
someone used ZMQ_RECONNECT_IVL to set the reconnection interval to 10ms.

With the patch what he would get is reconnection starting at 10ms and 
backing off up to 100ms.

I would suggest making default for ZMQ_RECONNECT_IVL_MAX zero, which 
would mean "do not apply backoff".

Yes. There are discrepancies in the docs, The patch seems to remove some 
of the existing documentation.
