   Returning EINTR really only applies to read() and write() (and open()) functions as covered
by #669 .  In other places, EINTR can be ignored.
   
   open() and close() should also return EINTR.  But i don't think that is very meaningful
for close since most people ignore the return value from close().
   
   But, on the other hand, ECANCELED can never be ignore under any condition.
