Introducing Curl_expire_latest(). To be used when we the code flow only wants to get called at a later time that is "no later than X" so that something can be checked (and another timeout be added). The low-speed logic for example could easily be made to set very many expire timeouts if it would be called faster or sooner than what it had set its own timer and this goes for a few other timers too that aren't explictiy checked for timer expiration in the code. If there's no condition the code that says if(time-passed >= TIME), then Curl_expire_latest() is preferred to Curl_expire(). If there exists such a condition, it is on the other hand important that Curl_expire() is used and not the other. Bug: http://curl.haxx.se/mail/lib-2014-06/0235.html Reported-by: Florian Weimer
