   I have a somewhat fuzzy idea of what happened here. Reading a
   directory up to some offet, remembering the offset, closing the
   directory, re-opening it and starting off at the remembed offset
   does not work for AFS directories.  It may also not work for NFS
   directories although I am not sure of that.  The system call that
   does work is is getdirentries, or you can read and cache the entire
   directory just once.

It isn't guaranteed to work on U*x directories either.  Directory
blocks could be compressed, messing up the pointer.
