This function assumes that in a parallel context all functions trying to modify the context call this function. If that happens, then deadlocks are avoidable, as the function can be invoked recursively without creating a deadlock and this function would serialize the execution of the potentially dangerous section -assuming all acquired locks are scoped and no coroutine-like behavior is present.
