[Zope] BUG with a patch

Hi, the way the manage_renameObjects() method was coded made it impossible to exchange two objects ids in one pass, e.g. rename Obj1 to Obj2 and Obj2 to Obj1. The attached patch seems to correct this problem, however a better temporary id construction method is needed. I've tried to submit it to the colector but I don't know if it succeeded. hoping this will help Jerome Alet
