I'll note here, too, that I didn't add all the missing core types, only
the ones that weren't iterators, descriptor internal stuff, or list
comparison wrappers. For any of those that are at all possible to
access from python code, I think they ought to show up somewhere, but
I'm not convinced __builtin__ is the right place. Also the ones with
"-" in their name need to be renamed.

Improved it slightly, and found another set of problems. Some modules
have a function bound in place of the type:
<select.poll object at 0x401cdea8>
>>> isinstance(select.poll(), select.poll)
TypeError: isinstance() arg 2 must be a class, type, or tuple of
classes and types
<built-in function poll>
Here's the list of these:
select.poll not a type.
mpz.mpz not a type.
itertools.tee not a type.
_csv.reader not a type.
_csv.writer not a type.
md5.md5 not a type.
cPickle.Pickler not a type.
cPickle.Unpickler not a type.
mmap.mmap not a type.
xreadlines.xreadlines not a type.
