Comment 7 for bug 978432

I've reproduced this error:

05-04T15:42:32 Error checksumming table test.multi_resource_apt: Possible infinite loop detected! The lower boundary for chunk 1 is <1> and the lower boundary for chunk 2 is also <1>. This usually happens when using a non-unique single column index. The current chunk index for table test.multi_resource_apt is resid which is not unique and covers 1 column.
