Keep in mind that D's allocator includes a garbage collector. To really 
do an apples-to-apples comparison, your benchmarking code should create 
lots of temporary objects. In D, the GC will handle all allocations and 
de-allocations. In C++, your objects will have to be manually created 
and destroyed.

I'd be more interested in those kinds of benchmarks than in the kinds of 
micro-benchmarks that just compare the speed of D allocation with the 
speed of C++ allocation.
