On a whim I decided to change the transport protocol that the Client
for NFS uses and my problem has gone away. By default "TCP+UDP" is
used, but if I set this to just UDP or TCP (via nfsadmin client), and
then restart the Client for NFS service, NFS largely works as
expected--with UDP apparently providing a bit higher throughput over
my WLAN. I haven't tried changing nfsd's flags on the server side
instead, but this might work as well.
Why "TCP+UDP" works for FreeBSD is unknown to me, but I'm content now.
I guess it's one of those interoperability issues...
