Why on earth is this allowed?  I have no idea how useful an non-initiaized class is.

So instead of checking circular inheritance, I would propose to simply disable Class.allocate.

Bug #6863: Class#initialize infinite loops when passed self

=begin
The following code sends Ruby into an infinite loop:

    x = Class.allocate
    x.send :initialize, x

The problem appears to be in rb_class_initialize (object.c:1564) when Ruby attempts to call (({#inherited})) on the newly created class. The method lookup infinite loops as it tries to descend the ancestor chain.

This should probably throw a (({TypeError})) instead.
