Did I ? I don't think I suggested this patch, only pointed some
existing ones.

I don't quite understand this one. While indeed with musl everything is
in libc.so, it's not the case for glibc and uClibc. Doesn't this break
stuff for glibc and uClibc ?

Any chance to submit this upstream so that we get some kind of review
from the valgrind maintainers ?

Thanks,

Thomas
