Replying to [comment:5 stippi]:
> One possible solution could be to export the runtime loader global
locking functions in runtime_loader_private.h and make sure that the
runtime loader lock is already locked before acquiring the default locale
roster lock whenever it would deal with add-on and image functionality
while holding it.
No, the problem really is the runtime loader locking. It uses a single
mutex which it acquires whenever it does, well, anything really. While for
the most part that is questionable just for performance reasons, when
calling the shared object initialization or finalization functions this is
actually a problem, since those may execute any kind of code which doesn't
even have to know that is was called in that context.
The runtime loader locking has to be rethought. Maybe a two level locking
would already do the trick: One lock to protect the image lists and one
lock per image.
