+B<3.> collectd handles I<SIGCHLD>. This means that python won't be able to
+determine the return code of spawned processes with system(), popen() and
+subprocess. This will result in python not using external programs like less
+to display help texts. You can override this behavior with the B<PAGER>
+environment variable, e.g. I<export PAGER=less> before starting collectd.
+Depending on your version of python this might or might not result in an
+B<OSError> exception which can be ignored.
