Yes it is, good to point this out.

This is why Pyro has been using a different (and safe) serializer by default for a while
now. You have to plow through the usual security warnings in the docs and make a
conscious effort in your code to enable the pickle serializer if you really want/need it.

Pyrolite also contains a Java and .NET version of that safe serializer so you should not
be using pickle at all when dealing with Pyro, but its implementation is there. And the
pickle code can be used independently.
