With execution times that short, you're really comparing the startup 
time of a D application vs. a C++ application.  And D application 
startup time includes the initialization of a garbage collector, in the 
default case.  If you really wanted to compare apples to apples here I'd 
rip out the default GC and replace it with one that has no 
initialization cost.
