Thread-Safety

QPromise is thread-safe and can be copied and accessed across different threads. QPromise relies on explicitly data sharing and thus auto p2 = p1 represents the same promise: when p1 resolves, handlers registered on p1 and p2 are called, the fulfilled value being shared between both instances.

::: warning IMPORTANT While it's safe to access the resolved value from different threads using then, QPromise provides no guarantee about the object being pointed to. Thread-safety and reentrancy rules for that object still apply. :::
