Description
The platform dependency architecture used by the Copy class has led to a lot of duplication of code.  There is no reuse of code across platform subsets; instead, each platform has it's own copy, even if it's the same as several others.  And this may have led to the usual small skews over time, where differences of non-obvious importance have crept in.
