-- make rcu wait when its buffer gets full, instead of crashing
-- fix makefile to compute dependency info as a side-effect of compilation (-MF)
+memory manangement
+------------------
+- allow threads to dynamically enter and exit rcu's token passing ring
+- augment rcu with heartbeat manager to kill and recover from stalled threads
+- make rcu try yielding when its buffer gets full
+- alternate memory reclamation schemes: hazard pointers and/or reference counting
+- seperate nbd_malloc/nbd_free into general purpose malloc/free replacement
+
+quality
+-------
+- verify the key memory management in list, skiplist, and hashtable
+- transaction tests
+- port perf tests from lib-high-scale
+- characterize the performance of hashtable vs. skiplist vs. list
+- validate function 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 
-- test ht
-+ optimize tracing code, still too much overhead
-- use NULL instead of a sentinal node in skiplist and list
-- make interfaces for all data structures consistent 
+- 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 nstring keys in the list/skiplist nodes
+
+features
+--------
+- allow values of 0 to be inserted into maps (change DOES_NOT_EXIST to something other than 0)
