I don't see immediately why, but since 3877bf2e323 test_builtin and
a couple of other tests leak in refcounting mode:

hg up 8a5742b7a14d
make distclean && ./configure --with-pydebug && make
./python -m test -uall -R :: test_builtin
[1/1] test_builtin
beginning 9 repetitions
123456789
.........
1 test OK.

hg up 3877bf2e323
make distclean && ./configure --with-pydebug && make
./python -m test -uall -R :: test_builtin
[1/1] test_builtin
beginning 9 repetitions
123456789
.........
test_builtin leaked [880, 880, 880, 880] references, sum=3520
1 test failed:
test_builtin

Yes, see 9e7f6ddc0d76 for the fix.

[skrah]

Ah, thanks for the pointer. 9e7f6ddc0d76 is clean, but default still
leaks. Next attempt:

OK: d2460ff173ff
Leak: 3b2856d8614b

test_dict leaked [12, 12] references, sum=24
test_builtin leaked [24, 24] references, sum=48
test_unittest leaked [970, 970] references, sum=1940
test_doctest leaked [351, 351] references, sum=702
test_doctest2 leaked [50, 50] references, sum=100

[benjaminp]

Okay, hopefuly fixed now.

[benjaminp]

I think I've nailed them all now.

[skrah]

Nice. 0554183066b5 is completely clean except for a leak in
test_curses. I think that one may be due to the fact that I'm
running the tests in an ssh terminal.
