I found and fixed a small bug that only shows up under the most precise 
conditions. It will cause a crash if it is tripped. You can cause the bug 
by:


1. point a hazard pointer in Thread A to node A
2. enqueue node A on a thread B's SMR cache
3. join Thread B
4. shutdown AppCore


When AppCore shuts down it goes though all of the SMR structures and calls 
"ac_free" on the nodes. This is the bug. It should not call "ac_free", 
instead it needs to call "ac_thread_cpu_node_cache_push_no_free".


Its fixed and you should probably re-download. This is one of those bugs 
that could hideout for a long time before anybody's experiments actually 
suffered from it.
