destroyStoreEntry

FREE destroyStoreEntry

One of the three methods to get rid of an unlocked StoreEntry object. This low-level method ignores lock()ing and release() promises. It never leaves the entry in the local store_table. TODO: Hide by moving its functionality into the StoreEntry destructor.
