It is a fallacy that EVERYTHING (e.g. libc) needs to be dynamically
linked to support that feature.  A single, self contained library
that might even be sparse WRT memory isn't going to hurt much.

A compromise that supports both a 'feature' and performance
seems to be appropriate.  Making everything shared (with
the sparse allocation of .data, and .text somewhat) to implement
a specific feature is certainly wasteful.

All or nothing isn't the optimal answer here.
