// Python on free threaded builds says this

//
//  For thread-safety, the free-threaded build requires that only
//  Python objects are allocated using the object domain, and that all
//  Python object are allocated using that domain.
//
// This turns out to be important because the GC implementation on
// free threaded Python uses internal mimalloc APIs to find allocated
// objects. If we allocate non-PyObject objects using that API, then
// Bad Things could happen, including crashes and improper results.
// So in that case, we revert to standard C++ allocation.
