Python doesn't seem to expose a mechanism for asking for the '%p' form
from Python:

  >>> print '%p' % id(object())
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ValueError: unsupported format character 'p' (0x70) at index 1

Stackoverflow[1] suggests as an alternative that we avoid the '%p' format
character and use the following (its example uses 'printf'):

  #include <inttypes.h>
  #include <stdint.h>
  ...
  printf("%016" PRIxPTR "\n", (uintptr_t)ptr);


I prefer your workaround, frankly:  I'd rather interoduce the weird code
in the tests than in C.
