Quoting http://mail.python.org/pipermail/python-dev/2004-November/050049.html:
Python doesn't promise to return a postive integer for id(), although
it may have been nicer if it did.
does anyone remember if there were any big changes in pymalloc between
the 2.1 series (where it was introduced) and 2.3 (where it was enabled by
default).
or in other words, is the 2.1.3 pymalloc stable enough for production use?

Yes. (Was it really 2.1? Time flies!)

can anyone explain the struct.pack and ZODB use cases? the first one
doesn't make sense to me,
Not deep and surely not common, just possible. If you're on a 32-bit
box and doing struct.pack(...i..., ... id(obj) ...), it in fact
cannot fail now (no, that isn't guaranteed by the

Yes, huge -- few original lines survived exactly, although many
survived in intent.

I hope to have a new patch (which makes PyExc_Exception new-style, but
allows arbitrary old-style classes as exceptions) soon. It may even
pass bits of make test :)
Done: http://www.python.org/sf/1104669
My design decision was to make Exception new-style. Things can be
raised if they are instances of old-style classes or instances of
Exception. If this meets with general agreement, I'd like to check
the above patch in.

After I finally understood what thread-safety guarantees the Python
memory allocator needs to provide, I went and did some hard thinking
about the code this afternoon. I believe that my modifications provide
the same guarantees that the original version did. I do need to declare
[Tim Peters]
As I said before, I don't think we need to support this any more.
More, I think we should not -- the support code is excruciatingly
subtle, it wasted plenty of your time trying to keep it working, and
if we keep it in it's going to continue to waste time over the coming
years

I'm not certain it is acceptable to make this assumption. Why is it
not possible to use the same approach that was previously used (i.e.
leak the arenas array)?
Do you have something else in mind? I'll talk with Martin about it if
he still wants to. Martin, this
