Thank you.

I saw the benchmarks with it, but can't remember if I saw one where it was
a comparision between the two malloc implementaions. Was there one and how
much did it help?

Hmmm, do we need to bump the libc minor version or is it not needed?
It would help to easily find out if one is using the new malloc and as
you said there are maybe some behaviour changes which may varent that
we bump the version.

Do you have an example of such a bad behaviour?

Thank you,
