  Modified files:        (Branch: RELENG_6)
    lib/libc/yp          yplib.c 
  Log:
  MFC 1.50:
  
  - Bump _yplib_timeout limit from 10 to 20 seconds to better handle
    packet loss when talking to a NIS server.
  - Set 1 second retry timeout to further realistically handle UDP
    packet loss for yp_next packet bursts.  If the packet hasn't come
    back within 1 second its rather unlikely to come back at all.  There
    is still back-off mechanism in RPC so if there is another reason
    than packet loss for the lack of response within 1 second, the NIS
    server will not be totally bombarded with requests.
  
  This reduces the risk of NIS failing with:
  
          yp_next: clnt_call: RPC: Timed out
  
  considerably.  This is mainly a problem if you have larger NIS maps
  (like at FreeBSD.org) since enumerations of the lists will cause a UDP
  packet bursts where a few packets being lost once in a while do
  happen.
