OK, if that's the case, seems like a bug in the original code, not
related to Java-style finalisation, so I would do that in a separate
patch.  Though libc probably allocates stuff with malloc and frees it
with free, and we call regfree to tell libc, so I think we should be
fine?

Greetings,
Maxime
