    lib/libc/resolv      res_send.c 
  Log:
  Only reject file descriptors higher than FD_SETSIZE if we are not using
  poll(2) or kqueue(2).  Previously we rejected fd's higher than FD_SETSIZE
  for kevent(2), and larger than sysconf(_SC_OPEN_MAX) for poll(2).  However,
  the check for poll(2) wasn't really needed.  open(2) and socket(2) won't
  return an fd you can't pass to either poll(2) or kevent(2).  This fixes
  a but where gethostbyname() would fail if you had more than 1023 files
  open in a process.
