Today my attempts to fix some reference leaks related to sys.flags and
sys.float_info caused the test to fail. A single init/final cycle worked
but the second cycle broke.
The test also shows an issue in Python 3.0. The double linked reference
list is broken:
$ ./test_reinit
round 1
[24676 refs]
round 2
[25588 refs]
round 3
* ob
object : <refcnt 0 at 0x82248e8>
type : str
refcount: 0
address : 0x82248e8
* op->_ob_prev->_ob_next
object : <refcnt 0 at 0x82248e8>
type : str
refcount: 0
address : 0x82248e8
* op->_ob_next->_ob_prev
object : bytearray(b'')
type : bytearray
refcount: 1
address : 0x839ab98
Fatal Python error: UNREF invalid object
