  <assertion id="1" tag="ref:XSH6:26693:26695">
   nanosleep() causes the current thread to be suspended until either:
    1) the time interval in rqtp passes
    2) a signal whose action is to terminate the process or invoke a signal
       catching function is delivered to the current thread
  </assertion>
  <assertion id="2" tag="ref:XSH6:26696:26699">
   Unless nanosleep() is interrupted (as in 2) above), nanosleep() must always
   suspend the process for _at least_ the time interval in rqtp - as 
   measured by CLOCK_REALTIME.
   [Occasionally, the time could be > rqtp interval because of 
   scheduling/rounding.]
  </assertion>
  <assertion id="3" tag="ref:XSH6:26700:26700">
   nanosleep() does not effect the action/blockage of a signal
  </assertion>
  <assertion id="4" tag="ref:XSH6:26702:26703">
   nanosleep() returns 0 if it returns because the time interval in rqtp
   has elapsed
  </assertion>
  <assertion id="5" tag="ref:XSH6:26709:26709 XSH6:26730:26730">
   nanosleep() returns -1 on failure or if interrupted
  </assertion>
  <assertion id="6" tag="ref:XSH6:26713:26714">
   nanosleep() sets errno to EINVAL if rqtp contained a nanosecond value
   below 0 or above (or equal to) 1,000 million
  </assertion>
  <assertion id="7" tag="ref:XSH6:26704:26708 XSH6:26712:26712">
   nanosleep() sets errno to EINTR if it is interrupted by a signal.
   Also, if rmtp != NULL, rmtp will be set to the time remaining (i.e., 
   requested time - time slept).  Otherwise, time remaining is not
   returned.
