Running regrtest.py with coverage option seems to be broken for the py3k branch at the moment. Run the following commands on the shell:
wget http://svn.python.org/snapshots/python3k.tar.bz2
tar xjf python3k.tar.bz2
cd python
./configure --enable-unicode=ucs4 --with-pydebug
make coverage
./python.exe Lib/test/regrtest.py -T -N test_urllib
This gives the following output:
[1/1] test_urllib
Not printing coverage data for 'Lib/test/regrtest.py': [Errno 2] No such file or directory: 'Lib/test/regrtest.py'

I'm testing on Mac OS X 10.6.5.
Attached is the complete log of the shell session.
This bug might be related to issue 10329, as the failing line was introduced in r86303.
OK, I reran the test with::
./python -mtest.regrtest -T -N test_urllib
and this does indeed produce coverage files (for _abcoll, _weakrefset, abc, base64, codecs, collections, contextlib, functools, genericpath, hashlib, locale, mimetypes, os, posixpath, quopri, random, re, sre_compile, sre_parse, ssl, stat, tempfile, textwrap, trace, uu, warnings).
However running the complete test suite via::
./python -mtest.regrtest -T -N -uurlfetch,largefile,network,decimal
fails with::
Not printing coverage data for '/tmp/tmp0fdr9o/t4/sub/subsub/__init__.py': [Errno 2] No such file or directory: '/tmp/tmp0fdr9o/t4/sub/subsub/__init__.py'
