I'm going to test it out this weekend, but if I do get the wrong

Doesn't "dlopen" open the current image if "null" is passed?
No, it opens the image for the main program, even if called from a shared
lib.
And that void* which is returned is actually a "mach_header*", if I
recall correctly.
Not sure if this is true.
This works for sure in terms of getting "a" mach_header*, but I still have
to check if visibility(hidden) allows each shared lib to have it's own
copy of "_symbol":
__attribute__ ((visibility("hidden"))) static int _symbol = 1;
Dl_info info;
if(dladdr(&symbol, &info))
const struct mach_header* myHeader = cast(const struct
mach_header*)info.dli_fbase
