There might be issues if you are calling another DLL from inside the 
(non-shared) static constructors and that DLL also uses TLS. In 
DllMain(DLL_PROCESS_ATTACH), each existing thread is initialized by just 
swapping the TLS data of the DLL and then running the module 
initialization. So if another DLL is called, it will only see the TLS of 
the thread that called DllMain.

I don't think anything in this code has changes recently. Is this a 
regression from the last dmd version?
