So what's your exports and fstab lines? I am worried I need to set some 
other parameters. Mine are:
exports:
/data1/Recordings 
192.168.1.0/24(rw,async,anonuid=109,anongid=119,no_subtree_check)

fstab:
192.168.1.9:/Recordings /mnt/backend nfs 
nfsvers=3,_netdev,timeo=14,intr   0   0
bindfs#/mnt/backend /data1/Recordings fuse 
_netdev,owner=howard,group=howard,perms=0000:u+rwD:g+rwD:o+rD   0 0

I still get freezes though. With and without the patch. The back-end is 
now quiet but the front-end complains
