Not unless it is running in its own thread. In that case, there will be 
a reference to the object held within the thread - for example in a 
local variable.

However, if the object exists solely to be shared by DRb, then yes you 
will need to keep a handle to it to stop it being garbage-collected. 
That's because DRb uses _id2ref to locate objects via just their id.
