is this plugin compatible with DreamPress?

This plugin is automatically installed on DreamPress by default. Unfortunately, I always run into trouble with it, and deleting it resolves the problems. For example, today I upgraded a client site to DreamPress, then I wanted to remove one plugin and install another. I tried repeatedly to deactivate the first plugin, without success. As soon as I deleted wp-content/object-cache.php, I was able to deactivate and delete the first plugin. I then installed and activated the second plugin, and everything was working correctly. I then reinstated wp-content/object-cache.php, and I was dumped out of the Dashboard to the login screen. After logging back in, an error message appeared saying a plugin was missing and had been deactivated. On the all plugins page, both the plugins I was working with showed as present but deactivated. I once again deleted wp-content/object-cache.php and everything was back to working correctly.

Am I misunderstanding the use of this plugin? Is it not meant to be used on a site that’s being worked on? Is it just a problem with DreamPress?
