AFAIK there are no known leaks with these Nokia tools.

To measure and graph resource usage changes in the whole system,
you can use sp-endurance:
http://wiki.maemo.org/Documentation/devtools/maemo5/sp-endurance
http://wiki.maemo.org/Documentation/devtools/maemo5/sp-endurance-postproc

The docs for the newer Harmattan version are here:

To analyze the leakage... If it's about memory, Valgrind Memcheck
and Massif tools might help you if pointers are lost or leak is large:
http://wiki.maemo.org/Documentation/devtools/maemo5/valgrind

For smaller and non-memory leaks sp-rtrace & functracer are most
likely best alternatives:

Sources for the sp-* tools are here:

(Debian/Maemo packaging is typically in the "maemo-packaging" branch.)
