This avoids a regression for issues like #334 where high speed repeated connections eventually run the HTTP client out of sockets because all of theirs end up in time_wait. Maybe the trade-off here is suboptimal, but if both choices will fail then we prefer fewer changes until the root cause is solved. Rebased-From:1a25a7edf87d2cb48511Github-Pull: #5674
