SPUG: File locking with flock and NFS

This thread slipped under my radar, but in case anyone still cares, I can
confirm that was the case as of Nov/00 at least. We tried to "use fcntl" on
an all-Linux network where each server/client had patches of nfsd and
nfslock up-to-date at the time, and the flock function would not
successfully maintain file locks under NFS (files would be written to
simultaneously).
