behlendo d46630e0f3 The first locking issue was due to the semaphore I used. I was trying 
to be overly clever and the context switch when the semaphore was busy
was destroying performance.  Converting to a simple spin lock bough me
a factor of 50 or so.  That said it's still not good enough.  Tests
show bad performance and we are still CPU bound.  The logical fix is
I need to implement per-cpu hot caches to minimize the SMP contention.
Linux and Solaris both have this, I was hoping to do without but it
looks like that's not to be.
