flock() .. hmm yeah, I discoverd trouble with sendmail as well, it rings 
my bell. At least I know where to look for digging in the code finding 
clues about why. 

You say flock() doesn't work with rpc.lockd running. I observed running a 
pxe client running fbsd 5.[45] being served by nfs-box running 5 (and 4 
nowadays because of asr0 trouble due to geom) having disabled rpc.lockd 
the box doens't let me run adduser, but with rpc.lockd enabled it's fine 
with 'em. Is that strange or am I missing (some) insight about this matter

Interesting observation.
