std.concurrency actually uses Variant as the transport mechanism 
for all messages, and this is most likely the cause of your 
problem.  If this is just to make a class pass type checking for 
transport, casting to shared is probably a better bet.  The real 
solution is to make std.concurrency effectively allow uniquely 
referenced classes to be transferred, but that's a bit farther 
out.
