ModifiableMapFromIMap<K, V> class
The ModifiableMapFromIMap is a safe, modifiable Map that is built from an IMap. The construction of the map is fast at first, since it makes no copies of the IMap items, but just uses it directly.
If and only if you use a method that mutates the map, like add, it will unlock internally (make a copy of all IMap items). This is transparent to you, and will happen at most only once. In other words, it will unlock the IMap, lazily, only if necessary.
If you never mutate the map, it will be very fast to lock this map back into an IMap.
