That's probably not a good technique.  Most of the time object files have 
timestamps in them so they never compare properly.

One thing to look at is the memory synchronization/locking routines.  I 
was looking at running the kernel in RMO mode and found that the memory 
barriers used in the mutex code are just... wrong.
