sommerfeld 3267e5e87d Probable fix for PR7943: lookups fail spuriously over NFS.
The problem was due to an interaction between the doomed unmounts done by
amd and getnewvnode.
I convinced myself that it's ok for getnewvnode() to do a sleeping vfs_busy().

Tested with multiple builds running while another process attempted to unmount
/usr once a second.
