In principle, sure. You can have many references to an object. In 
practice, I don't know how SQAlchemy does things so I cannot say if it 
allows this.

Python's garbage collector is thorough. An object with zero references 
is almost immediately removed from the interpreter's allocated memory. 
Gone. No shadows. No replicas. Gone is gone.

It doesn't matter what kind of object it is. It might matter if you were 
writing C++ where you have to manage memory yourself. This is Python. 
Let Python handle managing it's memory.
