The technique I was thinking of here is the --wrap option in the 
ld linker [1] (See the bottom of the page).  I use this in my 
microcontroller programming to override malloc and friends for 
devices that have discontinuous memory and no MMU.

I tried this on my Linux desktop, and while everything compiled 
and linked without errors, it resulted in a segmentation fault at 
runtime.  But where I have failed, others may succeed.  I tested 
with LDC and GDC, but not DMD.
