The results are a bit surprising to me :
 - wm(4) still starts in the 'detached' state after becoming up.
 - `ifconfig -w` consequently does not wait at all.

The big difference is that mount_nfs does not report the
"rpcbind to nfs on server: RPC: Port mapper failure - RPC: Unable to send"
error anymore, and merely waits a few (5 or so) seconds that the interface goes
through "detached" -> "tentative" -> "". (instead of the ~30s delay without
your patch).

So all in all your patch does the job, but I don't fully get why. And I'm still
a bit frustrated that ifconfig -w does nothing :)
