13 Would you elaborate on this? From a brief chat in IRC, you mentioned
14 Valgrind, but it looks like that issue has been solved:

18 jemalloc probably should be merged at glibc upstream, but I have zero
19 contact with glibc development, my Google searches have been fruitless
20 and I want to know what other people think about this. I think it would
21 be wrong to try to go to upstream with the idea if people downstream
22 don't like the idea. Not to mention, glibc is not the only libc in
23 Gentoo and this applies to each of them.
