Igor Novoseltsev reported a problem with the multi socket API and using timeouts and timers. It boiled down to a problem with libcurl's use of GetTickCount() interally to figure out the current time, while Igor's own application code used another function call. It made his app call the socket API timeout function a bit _before_ libcurl would consider the timeout to trigger, and that could easily lead to timeouts or stalls in the app. It seems GetTickCount() in general often has no better resolution than 16ms and switching to the alternative function QueryPerformanceCounter has its share of problems: http://www.virtualdub.org/blog/pivot/entry.php?id=106 We address this problem by simply having libcurl treat timers that already has occured or will occur within 40ms subject for treatment. I'm confident that there are other implementations and operating systems with similarly in accurate timer functions so it makes sense to have applied generically and I don't believe we sacrifice much by adding a 40ms inaccuracy on these timeouts.
