The only confirmed bug (reported from Drew Gallatin @ Duke) appears to be a
result of broken RPC64.  I _thought_ I had fixed it, but it would appear not.

This is kinda funny... we both make the same argument, but on different
sides :)

From what I recall (it has been far too long).  It was very similar in
design to the epics one.  Much of this is dictated via the RPC interface, but
we also both picked using the various QUEUE(3) macros.

I think the huge benefit with their code is greater testing, and likely better
overall design.  I don't recall if their code has the stuff for DOS "share"
NFS access.  Adding that to the rpics code was never finished due to a couple
of poor assumptions early on and needing to rework it later to fit.
