I understand that yes, pickle.loads() imports any necessary module but
only if they can be find in sys.path (like in any "import" statement).
Dynamic code loaded from a plugin (which we presume it is *not* in
sys.path) will not be loaded.
Quick check. Run in one console the following:
import multiprocessing
import multiprocessing.reduction
import pickle
pickle.dumps(multiprocessing.reduction.ForkingPickler)
<copy the output>
In a separated Python console run the following:
import pickle
import sys
'multiprocessing' in sys.modules
False
pickle.loads(<paste the dump here>)
'multiprocessing' in sys.modules
True
So the last check proves that pickle.loads imports any necessary module.

Are you sure that unpickle will import code? I thought it did not do that.
