+- make rcu try yielding when its buffer gets full, instead of throwing an assert
++ fix makefile to compute dependency info as a side-effect of compilation (-MF)
- investigate 16 byte CAS; ht can store GUIDs inline instead of pointers to actual keys
-- test ht
+- testing, testing, testing
++ support integer keys for ht
+- validate arguments to interface functions
+ 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
++ make the interfaces for all data structures consistent
+ make list and skiplist use string keys
+ optimize integer keys
-- sl_free() ll_free() ht_print()
++ ht_print()
+- iterators
+- characterize performance of data structures
+- experiment with the performance impact of not passing the hash between functions
+- experiment with embedding keys in the list/skiplist nodes
+- allow values of 0 to be inserted into maps (change DOES_NOT_EXIST to something else)
