The FunctionFactoryFinder(s) keep the registry of FunctionFactory instances
thread safe (so we do not create two accidentally). Beyond that your factory
could be used by multiple threads.
The Function's returned are placed into a Filter or Expression data structure
which is generally immutable, allowing it to be called from multiple threads
efficiently.
You have confused me a bit from switching your question from FunctionFactory
(single object in a register) to Function (many copies).
