How can it have GC when many instances are static objects, not allocated with PyObject_GC_VarNew()?

Martin v. Loewis writes:

Because the type type implements tp_is_gc (typeobject.c:1378), declaring static type objects as not being gc. In turn, garbage collection will not attempt to look at the GC header of these type objects.

I'm starting to really fear writing the documentation for all this! There are going to be a lot of mostly-inscrutible details to get right, and people are already asking the questions, so it really will need to be written down.
