Native Oberon/BlueBottle OS really a lot in dynamic modules, as 
everything
is dynamically loaded. As far as I know both operating systems 
have a global GC.

Not sure how Spin does it.

Singularity, uses local GC per process and does not support 
dynamic loading.

Bringing this into D's context, I imagine a solution for the GC 
would be to have it shared across all modules. The biggest 
problem I see, is that all shared libraries have to use the same 
D compiler, or a standard GC ABI needs to be defined.
