It is expected.  A d program must initialize both the C runtime and the D  
runtime, whereas a C program only needs to initialize C.

For example, D needs to call all the module ctors and do the import cycle  
detection algorithm.

0.11 seconds is not unreasonable.  But I'll also stress that timings at  
this precision can be fairly volatile.
