The initial delay was after the user had logged in, at which point the 
directory would have all ready been mounted.   I always chalked it up as some 
sort of networking issue.   I never saw this happen on RHEL 3 or any earlier 
versions (RHEL,RH, or Fedora), and as I said it was spurious.  

I'm not incredibly well-informed about the internals of NFS as it normally 
just works for me.

Still interested in the OP's issue and the solution, if only out of curiosity.

Thanks,
