This is a known bug.  I just did a bit of a search and saw a couple of 
bugs that claim to be fixed and then one with the latest comment dated 
yesterday that wasn't.  Perhaps Jerry would comment on this (since he's 
always listed in the bug).  One bug mentioned the OS tweak you did.

Curious, do you have any idea how this breaks NFS?  I may have to do the 
tweak here and NFS simply cannot break.
