Most systems (at least, those who run any locking at all)
use a lock manager derived from NFSSRC3.2, which predated the
mods I made to support DOS file sharing and locking. (Can you
imagine running a status monitor on a PC? I thought not.)

NFSSRC4.0 should have this fixed; however there seems to be a bug with
certain versions of SunOS 4.0 w.r.t. the DOS sharing calls, and I'm
checking to see if it's in the reference port. As far as I know,
no commercial implementations of the reference port are shipping.
(Steve - is this true?)

You only need the new lockd/statd if you plan to run PC applications
such as Btrieve or "[pick your favorite word processor] for Networks"
which may break without a functioning sharing/locking capability.
If you don't care, just mount the drives with "No sharing control"
or "Read-only access" and PC-NFS will omit all lock manager calls.
(I.e. all opens succeed regardless of sharing restrictions, and all
LOCK requests are immediately granted without checking the server.)
