Comment(by wjp):
I think the ipython/sage output history might still be holding a ref
there:
{{{
sage: V = QQ^7
sage: V.rename('foo')
sage: del V
sage: import gc
sage: gc.collect()
60
sage: QQ^7
Vector space of dimension 7 over Rational Field
sage: V = QQ^7
sage: V.rename('foo')
sage: V
foo
sage: import gc
sage: gc.collect()
9
sage: QQ^7
foo
}}}
(I left out printing V the first time.)
I don't understand the impact of the version either... It might just be
affecting the GC algorithm in some subtle way due to different memory
usage, but I realize that's next to impossible to verify.
