How much of a performance penalty would we take on {slow,
memory-limited} machines?

Since we do not (like e.g. Macintosh sources used to) check for redundancy
with something like

#ifndef FOO_HEADER_H
#include <foo_header.h>

_before_ the preprocessor #include, we would read many headers multiple times.
