--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
We deliberately do not deallocate memory on process termination because the
kernel will do it for us. This is why leak tracers either have to model the
internal interfaces, or call __libc_freeres on process termination. In other
words, the Intel Inspector needs to be made tcache-aware.
