When Python is compiled with Valgrind support, release Unicode interned strings at exit in _PyUnicode_Fini(). * Rename _Py_ReleaseInternedUnicodeStrings() to unicode_release_interned() and make it private. * unicode_release_interned() is now called from _PyUnicode_Fini(): it must be called with a running Python thread state for TRASHCAN, it cannot be called from pymain_free(). * Don't display statistics on interned strings at exit anymore

@ericsnowcurrently: I'm not sure if interned strings are supposed to survive Py_Finalize(). I don't think so. Anyway, after Py_Finalize(), we cannot free interned strings anymore, since the code uses Py_TRASHCAN API which requires a valid Python thread state... but Py_Finalize() free all Python thread states! |
