FreeBSD 4 supported NFS locks only on the server side, but not on the
client side. FreeBSD 5 is supposed to support client-side locks as well,
but I haven't tried.

Linux has been fine for a long time now (I believe that with ext2/ext3,
NFS has been doing fine since 2.2.12 or so, for other file systems, XFS
and reiserfs in particular, NFS was a problem until late into 2.4).

The point is that NFS locking requires fcntl() and will not work with flock().
