PROBLEM: (HGO073056) (PATCH ID: OSF510-173)
********
This patch fixes a problem where threads can hang
while renaming files on nfs mounted filesystems.  This can
occur when two threads are renaming files, one from directory 
"a" to directory "b" and the other from directory "b" to "a".
A typical stack trace for a hung thread looks like:
   0 thread_block        
   1 lock_write          
   2 nfs3_rename         
   3 rename              
   4 syscall
