Class wrapping a marshalled object whose type is unknown locally.
If an object is returned by a method invoked over drb, but the class of the object is unknown in the client namespace, or the object is a constant unknown in the client namespace, then the still-marshalled object is returned wrapped in a DRbUnknown instance.
If this object is passed as an argument to a method invoked over drb, then the wrapped object is passed instead.
The class or constant name of the object can be read from the
name attribute. The marshalled object is held in the
Public Class Methods
Create a new DRbUnknown object.

err is the error message that was raised
when the unmarshalling failed. It is used to determine the name of the

Public Instance Methods
Create a DRbUnknownError exception containing this object.

Attempt to load the wrapped marshalled object again.
If the class of the object is now known locally, the object will be unmarshalled and returned. Otherwise, a new but identical DRbUnknown object will be returned.
