But the question is how badly we need such things in shared
libraries that we want to link with Exim. And how secure the
implementation will be (all sorts of attacks are possible when a
program permits loading of arbitrary shared libraries).
Implementing hooks for functions to be compiled in statically is,
IMO, simpler, more portable, safer, and exposes the program to
the very same bugs as shared libraries would (such as memory
leaks). And not much is lost.
