Yes I'm sure that Gregs' patch helps for the rename race it's meant to 
fix. However, I believe the main issue revealed at James' site is a race 
for the wait q struct (ref. waitq.c in autofs4). This struct has gone 
entirely unprotected in 2.4 until I syned my 2.4 patch with what I've done 
for 2.6. This is what James is using.
