Details

we have a lot of pointless qi calls. nsIFile->nsILocalFile(and friends) most nsIInputStream->nsSeekableStream QIs could be done away with. Not only do these qi, but they also are immediately followed by error checks. I think as a solution would be some static analysis soup and code that expands to something like static_cast<nsIDerived> foo = abstract;
I assume this would also catch cases like 575900 where a QI can be replaced with an *implicit* static cast.
