A question about the emutls support:
I guess it's not compatible with C/C++ emutls right now? So if we have:
test.c:
__thread int a;

and test.d:
extern(C) int a;

This wouldn't work right now?

I think it could be possible to treat thread local variables in
extern(C) code specially and hook it up with the standard GCC emutls.
This way we could make it work, however we likely can't make the GC
scan extern(C) thread local variables then.
