I would still try appending a "with gil" after the callback function
signature, just to be sure, like this:

    cdef void my_callback(void* whatever) with gil:
        ...

It doesn't need to use threads, but it may still release the GIL internally
(for whatever reason).

You can unset "LANG=" on the command line, as in

    LANG=  python

to disable translations.
