Thank you for this. One thing that you may like to consider is compiling
more packages with -findirect-dispatch -fno-indirect-classes. This has a
smallish performance penalty, but packages compiled this way have no link-
time dependencies on other packages. Instead, everything gets fixed up
at runtime.
