Checks for reference counting leaks during cleanup. Using explicit
reference counts lead to occasional false positives (at least in parallel
test setups). This test now should still test leaks correctly when
run e.g. with pytest-valgrind or pytest-leaks

Matches the expected output of a debug print with the actual output.
Note that the iterator dump should not be considered stable API,
this test is mainly to ensure the print does not crash.
Currently uses a subprocess to avoid dealing with the C level `printf`s.
