Log Message:
-----------
It turns out the LIBXML_TEST_VERSION macro calls xmlInitParser().
Therefore we must xmlCleanupParser(), or we risk leaving behind
dangling pointers to whatever memory context is current when xml_init()
is called. This seems to fix bug #3860, though we might still want
the more invasive solution being worked on by Alvaro.
