Well, I did not get any response, so I had to complete the work alone.
I am attaching a patch for a fully working version of jemalloc for msvc.
We are using this version for about a week, and it looks pretty good so far.
As I mentioned in my last email, I really hope that this patch will be
committed to git.
Comments/suggestions are more than welcome
