The code coverage report should include how often a line got executed,
not just if it got executed at all. This makes it possible to se
hotspots in the code.

BTW, if there's interest, I can change the code behind
http://coverage.livinglogic.de so that instead of importing the data
into a database, static HTML files are created, so that we can run the
job more often on one of the Python servers. Currently the job runs once
a month with

   ./python Lib/test/regrtest.py -T -N -R ::
-uurlfetch,largefile,network,decimal

and takes about one hour to run the tests.

The source code is available from
http://styx.livinglogic.de/~walter/python/coverage/PythonCodeCoverage.py

Servus,
