To send them across actors, they need to be wrapped in an '@unchecked
Sendable' type. Typically such a wrapper type would be be responsible
for ensuring its uniqueness or immutability.
Inferring Sendability for arbitrary types that contain Unsafe*Pointers
would introduce race conditions without warning or any explicit
acknoledgement from the programmer that the pointer is in fact unique.
