    1 That behavior was when Atom/Residues access was through ctypes, and the pointer reference occurred in Python code.  Those classes are now implemented in Cython and the pointer access occurs in compiled code.  I could put ipointer checks into the Cython code so that incorrect user maintenance of Python data produces a traceback instead of crashes/corruption, at an unknown cost in performance.
