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.
