I believe the fix for:
6622174: need to remove msvcr71.dll from the RemoveFile table
added many new unneeded entries to the RemoveFile table, which aren't actually part of the JRE that we're installing. For instance:
attach.map, which is found in the jre/bin directory, is not a file that gets installed with the JRE...but it's in the RemoveFile table.
Part of this investigation should determine if this impacts 6u10 performance, and if so, how much?
