PyPy used to contain a bug that causes infinite memory usage in one
particular circumstance (literally -- so in practice, infinite
swapping with no progress). It so happens that since about one month,
translating a PyPy may trigger it. This means that in order to
translate a PyPy, you need to run (either CPython or) a version of
PyPy that contains the fix, which was done November 11.
