This works exactly like PointerTo, except that the object is designed to be thread-safe: it is generally safe to make unprotected assignments to this pointer, in the sense that the last assignment will win and the reference counts will be properly maintained. More...

We also have the typecast operator to automatically convert ThreadSafePointerTo's to the required kind of actual pointer.
This introduces ambiguities which the compiler will resolve one way or the other, but we don't care which way it goes because either will be correct.

Returns an ordinary pointer instead of a ThreadSafePointerTo.
Useful to work around compiler problems, particularly for implicit upcasts.
