Cannot have more than 10 chunks in a single operation

What does this error message actually mean? We're seeing it in some test code exceptions when trying to deploy new code.

System.TypeException: Cannot have more than 10 chunks in a single operation. Please rearrange the data to reduce chunking.

resolved. apparently deleting 5 types of custom setting objects at once was being counted as 10. since DML statements allowed for 100 statements per execution, I ended up just splitting each delete into its own statement. i wouldn't want to do this with visualforce-driven logic, but for scheduled apex, it's fine.
