Yes, I suppose that this was good task for starting programming for
gnu/mach. 

And thanks, Richard, for mentoring me. You helped me a lot, especially
with your code style corrections. I'll try to keep all your suggestions.

Also I understood that virtual memory management is quite interesting
topic for me, so I'm going to work on it further.

Thank you. I'll sign up now.

Difference isn't big, but I disagree that it's just a noise, because
this difference is systematic and constant in some range. At least
according to tests that I made in September, but your results don't
disprove it.

Here are my results for "time ( cd gnumach−1* && dpkg−buildpackage)":
   slab      zalloc
38m28.290s 38m58.400s
38m38.240s 38m42.140s
38m30.410s 38m52.920s
