os_event_wait_time_low(): wait time calculation is messed up

    Details

      Description

      http://bugs.mysql.com/bug.php?id=72520

      In os_event_wait_time_low() the logic to calculate abs_time
      for wait is broken. The bug has been present at least since
      5.5. It gets acutely sensitized when sub-second wait intervals
      are passed. It is particularly relevant to us because the
      page_cleaner thread will mostly request sub-second wait
      intervals. This can potentially lead to a near tight loop
      behaviour of page_cleaner with much less sleep then what we'd
      actually expect.
