This fails for me in a DLL:

If I print out the tid, I find that its message box is null.
This is odd, since according the code in std.concurrency
there's nothing weird about how it gets a message box, it's
just `auto spawnTid = Tid(new MessageBox);`. So... `new` is
returning null???
The really weird thing is that a thread is spawned and func
starts executing. I just can't send it any messages without
crashing.

If you suspect `new` of returning null, a GC issue seems likely.
Is your DLL linked statically against druntime, thus having its
own GC? Or are you using a shared druntime (and thus GC) across
multiple binaries?
