I've updated to use the new branch.  I got the docs building, but
there are many more problems.  I won't re-enable the cronjob until
more things are working.

Ok, I disabled these, so if only they fail, mail shouldn't be sent
(when I enable the script).

There are other problems:
 * had to kill test_poplib due to taking all cpu without progress
 * bunch of tests leak (./python ./Lib/test/regrtest.py -R 4:3:
test_foo test_bar ...)
 * at least one test fails with a fatal error
 * make install fails

Here are the details (probably best to update the wiki with status
before people start working on these):

I'm not sure what was happening with test_poplib.  I had to kill
test_poplib due to taking all cpu without progress.  When I ran it by
itself, it was fine.  So there was some bad interaction with another
test.

Ref leaks and fatal error (see
http://docs.python.org/dev/3.0/results/make-test-refleak.out):
test_array leaked [11, 11, 11] references, sum=33
test_bytes leaked [4, 4, 4] references, sum=12
test_codeccallbacks leaked [21, 21, 21] references, sum=63
test_codecs leaked [260, 260, 260] references, sum=780
test_ctypes leaked [10, 10, 10] references, sum=30
Fatal Python error:
/home/neal/python/py3k/Modules/datetimemodule.c:1175 object at
0xb60b19c8 has negative ref count -4

There are probably more, but I haven't had a chance to run more after
test_datetime.

This failure occurred while running with -R:

See http://docs.python.org/dev/3.0/results/make-install.out for this failure:

I'm guessing this came from the change in exception args handling?
