background.php and Hosting Tos (DailyRazor)

Hello,

I've receive today this email from my hosting provider :

"Dear Customer,

We have found a background process in your applications.This violates our ToS agreement(http://www.dailyrazor.com/terms-of-service) in article p.4.12:
"You agree not to run any background and/or listening processes. You also agree not to engage in any activity (through your code, processes, jobs, etc) that will affect the server and/or customer accounts on the said server."

Next file has been disabled: /home/chess373/public_html/wp/omeka/application/core/background.php

Please update this ticket with explanations as soon as possible."

I search in the forum and I found this thread that suggest to change webhost :
http://omeka.org/forums/topic/csvimport-appears-as-though-it-is-working-but-no-upload-happens/page/2

Is this file is really need to work or if I remove it, what functionality is gone (other than csvimport) ?

Thanks.

The background.php file is mostly just used for plugins by default. CsvImport, actually, at the moment, isn't using it either.

Thanks,

Is there the only background process in Omeka ?
