Modern network-in-the-kernel OS's are very
difficult to turn into "real-time"
systems with much functionality. You ever have a NFS server go down
and tie up a campus full of workstations for minutes at a time?

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.
