While investigating stack overflow issue 268918 I found that the following situation leads to UI freezes and stack overflows: #ln -s . cyclic_link1 #ln -s . cyclic_link2 Cyclic links protection does not work for such case. It also won't work for other less trivial cases.
fixed, change sets 5550fb8a2b7b and 506cd546a8e9 on enum
