Compressing class files in the module library

I have an initial patch  to compress the classes of modules in the
module library. It essentially adds an option to "jmod create" so that
the classes of any modules installed into the library get compressed.
The patch also adds a build option to enable compression in the system
libraries of the images that the build generates.
Before finishing this I'd like to get some input on a few points. The
first is whether it's reasonable to enable compression when creating the
module library? The alternative is install time so that it's on a per
module basis. The former is less flexible but as the module library
format evolves it may not be feasible to have a mix of compressed and
The other question is suggestions for the option name. For now it's -9
or --enable-compression (-9 influenced by the zip -9 option for
compress better). I'm looking for better suggestions.
