That would really be comletely unnoticable and would only decrease zsh's
size by a few bytes.

Of course it can, at least on elf systems.  If you see

warning: Unable to find dynamic linker breakpoint function.
warning: GDB will be unable to debug shared library initializers
warning: and track explicitly loaded dynamic code.

that's probably because you use Linux and the binary ld.so.1.8.5
distribution.  With ld.so.1.8.2 it was possible and there were no such
warning.  I'm told that recompiling ld.so.1.8.5 with -g, or just simply not
stripping it would help here (I did not played with that).

And if you attach a runnig zsh which already loaded a module to gdb, you
can debug the loaded module.  Of course as gdb says you'll be unable to
debug the module initialisation process (i.e. the boot_... function).
