A convention of using talloc_tos() does not guarantee that we don't
leak memory. Just like long running async state contexts, talloc
stackframes can also be neglected. As mentioned in the other mail, my
preference would be to proceed with integration of valgrind memcheck,
massif and talloc_report into regular CI.
