Why does the python plugin insist on permissions?

[standaloneSA]

The python plugin cost me several hours of downtime on a very critical machine today.

Essentially, my WSGI web-apps were unable to be loaded by the www-data user because imports failed if the code lived in /usr/local/lib/python2.7/dist-packages

The reason was tracked back to this module which, as described by the readme:

• modulepaths is an array of paths where will be Collectd looking for Python modules, Puppet will ensure that each of specified directories exists and it is owned by root (and chmod 0750). If you don't specify any modulepaths a default value for given distribution will be used.

What is the reason for setting module paths to 750?
