No. 1 question: do you have a reproduceable test case of both behaviors?
Excerpts from Henning Thielemann's message of Fri Aug 17 08:10:02 -0400 2012:
> The doc of base-4.5:Foreign.ForeignPtr.addForeignPtrFinalizer states:
> "This function adds a finalizer to the given foreign object. The
> finalizer will run before all other finalizers for the same object which
> have already been registered."
> I do
> addForeignPtrFinalizer finalize1 fp
> addForeignPtrFinalizer finalize2 fp
> and let the finalizers print something when they are started.
> I get the output:
> This indicates that the newly added finalizer is run _after_ the
> finalizers that are already registered. Is this a documentation bug or a
> bug in the base library?
