Some notes about the leak: if the insertion into the uthash fails (because of an allocation failure), we need to free the just allocated entry. But the only way to check if the

failed, is to perform a new lookup: a bit costly, but we don't use that code in the fast-path. See also efb261aCredits for finding the issues to Philippe Antoine (@catenacyber) and its
