The following 3 easy one liners knock off a few more modules.
The first two should work on clean 4857, the last requires an ENH I sent
that move the benchmarking stuff to it's own class.

After Benchmarks is isolated, it can be unloaded, and then Morphic Demo
Games can be unloaded too (last reference to FreeCell).

None of these break any functionality that I know of.

ParserRemovedUnusedTemps moveTo: Module @ #(Squeak Language Exceptions
Core)
FileList removeSelector: #addFileToZip
Benchmarks moveTo: (Module fromPath: #(Squeak Technology Benchmarks)
forceCreate: true)
