+memory manangement
+------------------
+- make rcu yield when its buffer gets full instead of throwing an assert
+- alternate memory reclamation schemes: hazard pointers and/or reference counting
+- verify the key management in list, skiplist, and hashtable
+- seperate nbd_malloc/nbd_free into general purpose malloc/free replacement
+
+quality
+-------
+- transaction tests
+- port perf tests from lib-high-scale
+- characterize the performance of hashtable, list and skiplist
+- validate arguments in interface functions
+- document usage of the library
+- document algorithms
+
+optimization
+------------
+- investigate 16 byte CAS; ht can store GUIDs inline instead of pointers to actual keys 
+- shortcut from write-set to entries/nodes
+- use a shared scan for write-set validation, similar to ht copy logic
+- experiment with the performance impact of not passing the hash between functions in ht
+- experiment with embedding the keys in the list/skiplist nodes
+
+features
+--------
+- allow values of 0 to be inserted into maps (change DOES_NOT_EXIST to something else)
