Thank you for the contribution. I can see how this could be useful
in some limited embedded applications, but at this moment it doesn't
seem to be generally worth adding to the upstream code.

The patch does contain some cleanup bits for where the existing
code is not freeing stuff. This should be fixed, independent of
whether library support is added, because it would remove the number
of leaks reported when testing under valgrind. Could you resubmit
that part please.
