ython.org/pi...ril/015395.html
> A memory leak results when there is a PythonOption directive in the apache
 config file. Leak occurs when PythonOption is in either <VirtualHost>  or <
Directory> section.
> For each request, approx 25 bytes of memory is leaked per PythonOption dir
ective.
> Methodolgy (using top to gauge memory usage, 100,000 requests per test cas
e):
> def handler(req):
>     req.content_type = 'text/plain'
>     req.write('PythonOption test\n')
>     return apache.OK
> 1. No PythonOption directives:
>     1.4 % MEM
> 2. 50 PythonOption directives:
>     11.3% MEM
> 3. 100 PythonOption directives:
>      25.4 % MEM
> I know 50 or 100 PythonOptions is not likely in a production system, but it clearl
y demonstrate the leak.
