  This frees up a few global variables allocated by libxml2. A few
kilobytes at most, but if they get deallocated while somehow the library
is still in use, the application is very likely to crash.
  So never call this in a library.
  In an app the only safe place to call it is close to the exit
It's still useful to make sure there is no memory leak when running a
program under valgrind or equivalent memory checker.
