Microsoft not disposing of their own objects?

EDIT: Server is MOSS 2007 Enterprise, running SP1 and all patches up to, but not including, SP2. SP2 is coming soon.

In one of my SharePoint apps, I am getting this warning & stacktrace over and over (with different GUIDS): since it's only one of my apps, I assume there开发者_开发问答's something in my project's code, but SPDisposeCheck returns clean, and there's nothing in the logs that point to my code.

Any ideas on how I can track this down?

Error I'm getting:

Potentially excessive number of SPRequest objects (9) currently unreleased on thread 1. Ensure that this object or its parent (such as an SPWeb or SPSite) is being properly disposed. Allocation Id for this object: {1DFFC1ED-E69E-4580-8D7B-45EDB5C49188}

This is apparently expected behavior.
