Matthias Clasen 69fb3648b2 Tweak the file transfer portal _again_ 
This is a neverending story. I was seeing problems in tests where
the nested mainloop was picking up unrelated timeouts.

Break down and make this async. This changes the ordering in which
the (de)serializers are registered. If this is causing issues, we
can introduce priorities or something else.
