NFS under ultrix 4.2

[Oh no, not this again!]

Does anyone know if 4.2 has fixed the "getwd: can't open .." problem?
I can't find it mentioned in the release notes.  This usually occurs
on a nested NFS mount with root as the user.  For instance:

  # mount | grep brahma
  brahma:/ on /brahma type nfs (rw,hard,bg,retrans=6)
  brahma:/dal on /brahma/dal type nfs (rw,hard,bg,retrans=6)
  # pwd
  pwd: getwd: can't open ..

I'm really loathe to install 4.2 until I see a big win from installing it.
