Follow-up Comment #9, bug #19434 (project lwip):

With your patch we have 3 functions where rtime is modified
  tcp_slowtmr
  tcp_receive
  tcp_output_segment

In tcp_slowtmr rtime is only incremented.
  
In tcp_output_segment reset of rtime  occurs only once (timer is never
stopped).
  
In tcp_receive reset of rtime occurs on ACK of the new data.

It is necessary to reset rtime on retransmit somewhere...
