-- make rcu wait when its buffer gets full, instead of throwing an assert
+- 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
- testing, testing, testing
+ make the interfaces for all data structures consistent
+ make list and skiplist use string keys
+ optimize integer keys

- 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)
