If a garbage collection occurs during a garbage-collected extension class's deallocation, it may get double-freed (which is not always fatal but can cause issues much later if side effects are involved).

See http://trac.sagemath.org/sage_trac/ticket/13896 and https://groups.google.com/forum/?hl=en&fromgroups=#!msg/sage-devel/Wt7uxbDkh_A/4qhfm2ukBR0J for more context.
