I don't have an answer, but offer this observation: five boxen running 
2.6.17.8 doing six simultaneous

  bzcat /home/share/linux-2.6/patch-2.6.18-rc4.bz2|patch -p1

didn't burp.  The /home/share/ is an NFS export from another box running 
2.4.33-rc3a, me not sure if this was exercising any NFS locking as the 
NFS source file was only opened for non-exclusive read-only.

Grant.
