different test skipping reasons.
* test/bind.py

get_num_object_protections() and `num_protected_objects' for all
protectors but `FastGCProtector'.
(_GCProtectorTestCase._do_test_double_protection): Likewise.
(FastGCProtectorTestCase, RaisingGCProtectorTestCase)
(DebugGCProtectorTestCase): Use
NotifyTestCase.note_skipped_tests() to inform about test skipping,
don't just silently omit them for non-CPython.
2008-12-10 Paul Pogonyshev <[email protected]>

constant, based on whether Python implementation is CPython.
(NotifyTestCase.setUp): Disable additional tests if
`HAVE_CONTROLLABLE_GC' is false.
(NotifyTestCase.tearDown): Likewise.
(NotifyTestCase.collect_garbage): A different half-hearted
implementation GC.
* test/all.py (AllTestCase.test_gc): Test new
`StandardGCProtector' and `SlowGCProtector'. Test relevant

Use `StandardGCProtector' instead of `FastGCProtector'.
(AbstractGCProtectorTestCase.test_default_property_illegals):
Likewise.
(SlowGCProtectorTestCase): New test case.

(DebugGCProtectorTestCase): Only define if
`HAVE_FAST_IMPLEMENTATIONS' is true.
2008-10-06 Paul Pogonyshev <[email protected]>
* notify/gc.py (AbstractGCProtector): Declare without `__slots__'.
* notify/_gc.c (gc_module_initialize_state): Test and rely that
`AbstractGCProtector' class is defined without `__slots__',
i.e. gets `__dict__' and `__weakref__'.

`should_have_slots' argument and branch accordingly.
(AllTestCase.assert_is_class_tuple): New method.
(AllTestCase.test_bind): Use it for `BindingCompatibleTypes'.

Bug-fix: don't rely on two 42's being the same object.

incorporate whether `__signal' is set and whether it is an

case.
