    Waits for multiple handles. (Similar to 'select') Returns the handle which is ready.
    Returns `None` on timeout.

    Note that handles should be a list of `HANDLE` objects, not integers. See
    this comment in the patch by @quark-zju for the reason why:

        ''' Make sure HANDLE on Windows has a correct size

        Previously, the type of various HANDLEs are native Python integer
        types. The ctypes library will treat them as 4-byte integer when used
        in function arguments. On 64-bit Windows, HANDLE is 8-byte and usually
        a small integer. Depending on whether the extra 4 bytes are zero-ed out
        or not, things can happen to work, or break. '''

    This function returns either `None` or one of the given `HANDLE` objects.
    (The return value can be tested with the `is` operator.)
