  67  * This allows for 256 file descriptors: if NR_OPEN is ever grown beyond that
  68  * you'll have to change this too. But 256 fd's seem to be enough even for such
  69  * "real" unices like SunOS, so hopefully this is one limit that doesn't have
  70  * to be changed.
  71  *
  72  * Note that POSIX wants the FD_CLEAR(fd,fdsetp) defines to be in <sys/time.h>
  73  * (and thus <linux/time.h>) - but this is a more logical place for them. Solved
  74  * by having dummy defines in <sys/time.h>.
