New issue 1773: py3k: continuation.test_zpickle test_pickle_continulet_real_subclass triggers a CPython crash https://bitbucket.org/pypy/pypy/issue/1773/py3k-continuationtest_zpickle
test_pickle_continulet_real_subclass has been disabled on the py3k branch for now as it can trigger a seg fault when running under CPython.
It'll crash with a "Fatal Python error: GC object already tracked", or at least on OSX: "malloc: *** error for object 0x109620af0: pointer being realloc'd was not allocated"
continulets do some potentially 'evil' low level things but AFAICT nothing pypy's doing is at at fault here. The crash doesn't seem to occur on default even though the continulet implementations/tests are basically identical
