leftover pyc files

[Chris Kaynor]

If you can at least upgrade to Python 2.6, another option, if you
don't mind losing the byte code caching all together (it may worsen
load times, however probably not significantly), you can set
PYTHONDONTWRITEBYTECODE to prevent the writing of .pyc files.
Alternatively, again in 2.6+, you can also specify the -B command-line
argument. See http://docs.python.org/using/cmdline.html#envvar-PYTHONDONTWRITEBYTECODE
and http://docs.python.org/using/cmdline.html#cmdoption-unittest-discover-B
