qpopper and uw-mapd locking interaction in server mode

[Joe Maimon]

I am looking to make them work together, Blackberry users corrupting 
spool drops is becoming a real problem (easily fixed by removing top few 
lines of spool file that appear to be a partially deleted msg).

I understand that there are possibly two patchsets for locking, the ntua 
patch and one from Clifton Royston.

I would like to take a stab at these, so if anyone can point me at some 
resources, I would apppreciate it.

Thanks,

Joe
