[Rd] unserialize and eager execution

While debugging a network server I'm developing I noticed something unusual - call to unserialize() resulted in
an error about loading a namespace.

I was a bit taken back by this - why should unserializing an object cause a namespace lookup?
Are there any other side-effects of unserialize() that I should be cautious about? I've been
digging through the R_Unserialize() call, I haven't found the loadNamespace bit yet but I
assume its in there somewhere.

Is there anyway to guard against R eagerly evaluating serialized data (serialize()) being unserialized (unserialize()) ?
