I assume most of the changes are just moving code around - but it's impossible to see in github :-( So assuming this there is just the question of Dyld's lifetime vs that of DynamicLibraryManager: if we can tie the two then there's no need for checking whether Dyld has been initialized or not; it's guaranteed by the constructor. Would that be an option?

[Axel-Naumann]

Thanks for explaining!
