  11 // On Windows the GetExitCodeProcess API is used to get the exit code of a
  12 // process, but it's easy to mistake a process exiting with the code 259 as
  13 // "still running" because this is the value of the STILL_ACTIVE constant. Make
  14 // sure we handle this case in the standard library and correctly report the
  15 // status.
  16 //
  17 // Note that this is disabled on unix as processes exiting with 259 will have
  18 // their exit status truncated to 3 (only the lower 8 bits are used).
