avgtime profiles the whole process, right? It measures everything that 
is involved in that little program. At least OS starting the program, D 
runtime initializing, program interacting with the console, etc.

Since you're comparing algorithms, you need to take everything else out 
of the equation. A better approach is to use std.datetime.benchmark, 
which would repeat just the algorithm that you're interested in.
