Well... it turns out make the nlm rpc routines drop messages  was not 
that difficult.
Fairly straightforward actually....  basically copying working code in 
to other places
and  making things work just like the kNFSd does...

So that attached patch does the following:
1) Adds an internal nlm_lck_dropit error code.
2) Adds a  nlmsvc_dispatch() function that will drop message when the NLM
    procedure function returns nlm_lck_dropit.
3) Changes nlm_fopen() and nlm_lookup_file() to handle the nlm_lck_dropit
    error code.

Finally, I left in some of the truly helpful debugging statements. The 
ones that
were key in helping me figure out what was going on... Now I'm not one 
to force my
debugging style on anybody, but... having fh_verify() and exp_find_key() 
tell
us why they are failing is a good thing... imho...
