unit tests in a sorry state

There's a number of parts to this email, all of which relate to my
attempts to run Zope2 unit tests under Python 2.3.5c1

These are all with Python 2.3.5c1, built with 
gcc version 3.4.3 20050113 (Red Hat 3.4.3-14)
on a Fedora Core box with kernel  2.6.8-1.541 
and glibc version 2.3.3-87.

Running Zope 2.7.4's tests under Python 2.3.5c1 has a bunch of 
errors, most of which appear to be timezone related.

In addition, we have this warning on a box with PIE, and a Python
running in the top half of the address space:

Under svn trunk of Zope2, I get the following error:
Traceback (most recent call last):
  File "./test.py", line 920, in ?

line 91
    except:
          ^
IndentationError: unindent does not match any outer indentation level

This is a trivial error - I don't have write access to the repository any
more, so I can't fix it. add one space to that line.

Running the tests after this killed my machine after something gobbled up
hundreds of megabytes of virtual memory. After a reboot, I set a ulimit on 
memorysize to 250MB, I got one breakage, and a bunch of failures (also
timezone related). There were probably other problems after this test aborted,
but I'm not inclined to mess about with it.
