Tim... Please don't ever consider the NFS server issue and workstation
lock-ups an issue of real-time.

The network-in-kernel issue is one of preemption of kernel and some
other latency issues, but this is a kernel design issue -- not an NFS
issue.

The problem above is just NFS's screwed up stateless design.

      Three things never anger: First, the one who runs your DEC,
      The one who does Field Service and the one who signs your check.
