Class
Class
responsible for converting between an object and its id.
This, the default implementation, uses an object’s local ObjectSpace
__id__ as its id. This means that an object’s identification over drb remains valid only while that object instance remains alive within the server runtime.
For alternative mechanisms, see DRb::TimerIdConv
in rdb/timeridconv.rb and DRbNameIdConv in sample/name.rb in the full drb distribution.

This implementation returns the object’s __id__ in the local object space.

Convert an object reference id to an object.
This implementation looks up the reference id in the local object space and returns the object it refers to.
