  Modified:    lib/libc/yp  yplib.c
  Log:
  NIS client-side performance tweak:
  
  Each of the ypclnt functions does a _yp_dobind() when it starts and then
  a _yp_unbind() when it finishes. This is not strictly necessary and it
  wastes cycles: it means we do a new clnt_create() and clnt_destroy()
  for each yp_whatever() call. In fact, you can do multiple clnt_call()s
  using a single RPC client handle returned by clnt_create(). Ideally we only
  have to create a handle to ypserv once (the first time we call a ypclnt
  function) and then destroy it and rebind only if a call to ypserv fails.
  
  - Modify _yp_dobind() so that it only creates a new RPC client handle
    when establishing a new binding or when one of the ypclnt calls
    invalidates an existing binding and calls _yp_dobind() to establish
    a new one.
  
  - Modify the various ypclnt functions to only call _yp_unbind() if a
    call to ypserv fails.
