1 - make rcu wait when its buffer gets full, instead of crashing
2 - fix makefile to compute dependency info as a side-effect of compilation (-MF)
3 - investigate 16 byte CAS
4 - ht can store GUIDs inline instead of pointers to actual keys
5 - mem can keep tail pointers for free-lists and do O(1) appends
7 - optimize tracing code, still too much overhead
