It would be nice.  The trouble is that CPython is not the only Python.  
Jython, for example, uses the Java Runtime Environment for its virtual 
machine.  JRE doesn't have reference-counts, so Jython can't close files 
immediately after the last reference ends.  It seems guaranteed object 
cleanup would lock Python out of too many possible platforms.
