Each interpreter now has its own float free list:

  • Move tuple numfree and free_list into PyInterpreterState.
  • Add _Py_float_state structure.
  • Add tstate parameter to _PyFloat_ClearFreeList()
    and _PyFloat_Fini().

There no reference leak on the following tests which use subinterpreters:

./python -m test -j0 -R 3:3 test_capi test__xxsubinterpreters test_atexit  test_threading
