    In order to properly handle multiple threads and fork()-calls from C code
    (rather than os.fork()), Python should provide pthread_atfork()-like
    functionality: a function to call before a fork, to acquire any locks
    that need to be acquired, and a pair of functions to call after the fork,
    in the parent and the child, to release or re-allocate locks. The
    acquisitions should be re-entrant and should not require an existing
    threadstate. Also see <http://bugs.python.org/issue1590864\>.

    For reference, this is related to http://bugs.python.org/issue6721 but
    deals with the C API side of things for an atfork mechanism to be used by
    extension modules.
