I didn't, but that's because the wedged "client" in this case was my
primary NFS server which was NFS mounting a file system from our
'dogfood' system.  We (I should specify I actually had nothing to do
with this...) took down our test system to move it without making sure
all systems were properly unmounted, which resulted in wedging my
primary NFS server. 

I don't see why this wouln't have worked though, and I intend to find
out this week sometime using some of our test equipment. I'll let you
know!
