History
behlendo 44b8f1769f Add another kmem test to check for lock contention in the slab 
allocator.  I have serious contention issues here and I needed
a way to easily measure how much the following batch of changes
will improve things.  Currently things are quite bad when the
allocator is highly contended, and interestingly it seems to
get worse in a non-linear fashion... I'm not sure why yet.
I'll figure it out tomorrow.

        kmem:kmem_lock    Pass
