- make rcu wait 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 - 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 the interfaces for all data structures consistent + make list and skiplist use string keys + optimize integer keys - ht_print() - iterators
