Crate waitcache

The waitcache crate provides the WaitCache type, an ever-growing concurrent hash map with key-level locking granularity. A hash map of this kind is useful for memoizing highly expensive functions, such as those requiring disk or network accesses. Unlike other cache implementations, WaitCache only ever resolves a value once, preventing expensive computations from duplicating work.
