The pinning has to be a @trusted operation though to prevent 
multiple threads to access the GC local object.

If you want to do everything in @safe code you could use the same 
"isolated" mechanisms to allow pinning in @safe code.

Borrowed pointers remain scope limited when other threads access 
them, since the pointer is tagged as borrowed the type system can 
ensure that it isn't retained.

Another option would be for the dictionary to allow access 
through a callback that scope-restricts the object.
