Sharing data between multiple threads that each use a different 
instance of the D GC will definitely not work right, because each 
GC will only know to pause the threads and scan the roots that it 
has been directly informed of.

There is supposed to only be one instance of the D GC running per 
process. If you have more than one running then either you aren't 
linking and loading the DLLs correctly, or you have run into a 
serious bug in the D tooling.

I have found the gdb debugger on Linux often breaks horribly on 
my D code, especially when it is multi-threaded, and the debugger 
is only semi-usable. Maybe the Windows debugger is better now? (I 
wouldn't know, since I haven't used it in a while.) I think 
skepticism is warranted here.
