I had looked into this already over two years ago, and had to stop after
investigating a performance regression for two weeks and not getting
anywhere.

Also, nedmalloc fell unmaintained, so I don't necessarily think that it
would be a good idea to  spend a lot of time on it.

In the meantime, there is a much more viable contender: mi-malloc.
Preliminary tests suggest that its performance on Windows is at least as
good as nedmalloc's, and Windows was the use case for which we
integrated nedmalloc into Git's compat/ in the first place.

I have tentative patches to integrate it into Git for Windows, and
basically got side-tracked with other things. Expect to see something
regarding mi-malloc from me in September.

Ciao,
