I've added some debugging code to _Py_ForgetReference and now I'm
getting this:
$ ./reinit_test
round 1
[23832 refs]
round 2
[24558 refs]
round 3
* ob
object : <refcnt 0 at 0x821d728>
type : str
refcount: 0
address : 0x821d728
* op->_ob_prev->_ob_next
object : <refcnt 0 at 0x821d728>
type : str
refcount: 0
address : 0x821d728
* op->_ob_next->_ob_prev
object : buffer(b'')
type : buffer
refcount: 1

* refchain
object : <refcnt 0 at 0x81a1500>
type : NULL
refcount: 0
address : 0x81a1500
Fatal Python error: UNREF invalid object
Aborted
