That's kind of a scary tech note - but not as scary as the dyld
sources ;)
The other factor to consider is that the 3 different dylib models
that are
available all have different life cycle models. I wrote a series of
test
programs that explored the loading/unloading cycle for dynamic libs,
frameworks and bundles and they have different unloading properties.
My suggestion is to hook the mach load/unload entry points and dump
some stuff to the console log to make sure your frameworks are loading
and unloading the way you expect them to.

There was a change in the order terminators are called in 10.4.
Before 10.4 global objects were destructed in the same order they

the reverse order they were constructed.
Not related to this problem, there is also a problem with
initializers before 10.4. Basically, initializers are run too
lazily before 10.4. http://developer.apple.com/releasenotes/DeveloperTools/dyld.html
That is very good to know. Thank you for pointing that page out.
