Yes, that is understood.  Only what is required to implement a 
malloc replacement is within the scope of the project.

The project is pressed for time, so I'd like to stick with 
something known and well-documented.  Perhaps IAllocator is not 
the right solution in the end, but still, implementing it and 
seeing how it fits into druntime should inform future directions, 
and perhaps even elicit some new ideas.
