I don't think that I have an example off hand, I remember that we did find a few different cases of the handling. But, I suppose that some coverage is better than none.

DLL Storage and visibility are subtly different and while building on Linux may be easier, I expect that we will need to do more reverts for the Linux based pre-merge tests than with the Windows based pre-merge tests.
