The new keyword can leverage the shared keyword to place certain
objects in a shared GC, which can coexist with the local GC
without fundamental changes. ie std.concurrency already requires
that you pass shared objects, but casting won't cut it anymore
you'll actually have to duplicate the object on the shared GC
with .sdup or create it there with new shared. I don't need a
shared GC right now so I'm not pushing too much for it, I'm
satisfied with keeping a pointer of the object alive in the
thread it was created and that's all a thread local GC really
requires for concurrency to work
