Class representing a lock

The methods available for a specific lock type are only known by it's factory.

param: mixed $key - The lock key. The type of this is up to the lock_factory being used.
param: lock_factory $factory - The factory that generated this lock.

init_factory(lock_factory $factory)   X-Ref
Sets the lock factory that owns a lock. This function should not be called under normal use.
It is intended only for cases like {@see timing_wrapper_lock_factory} where we wrap a lock

get_key()   X-Ref
