I had to call off the experimentation with live users and resorted to 
running all IMAP connections from a single NFS client for now.  I was 
causing a little too much of a stir.  Here are the things I can remember 
trying:

negnametimeo=0 (no perceived difference)

acregmin=0,acregmax=0,acdirmin=0,acdirmax=0 (slowed down imap but 
otherwise no perceived difference)

stopped statd and lockd after changing dovecot to use dotlock (no 
perceived difference)

vfs.lookup_shared=0 (no perceived difference)

dovecot 1.1 (no better than 1.2 regarding this issue)


Did not try (yet?):

udp, nfsv4, freebsd 7

I feel compelled to keep the users happy for now while I look into the 
nfs director included with dovecot 2.0 designed to keep individual IMAP 
users on their own server, so I'm taking a stab at the recommended usage 
with newer software rather than more debugging with previous versions. 
I may return to other tactics if the future path slows down,
I'm still curious why things changed.
