Adding paths to the store can be slow due to I/O overhead, but especially when going through the daemon because of the round-trip latency of every wopAddToStore call. So we now do the addToStore() calls asynchronously from a separate thread from the evaluator. This slightly speeds up the local store, and makes going through the daemon almost as fast as a local store.
