I think this is arguably a reasonable first step, but working towards a 
compatible core still means two separate cores, which means not being 
able to use Tango and Phobos together in the same app.  So I'll admit to 
not completely understanding the reasoning behind this approach, but 
it's the only option so I'm happy to comply.  Frankly, I don't want to 
be stuck maintaining the Tango runtime from now until doomsday anyway :-)
