commit 4979e190653603f0f22dab90b92a4fab2a6fc5a9

    kernel - Implement degenerate timeout case for select() and poll()
    
    * When select() or poll() are called with no descriptors and only a
      timeout, call nanosleep1() instead of using tsleep() to generate
      a more precise time delay.
    
    * Significantly improves postgresql's performance.
