One possibiltiy is some kind of reentrancy bug, after all, this
happened since I subclassed stuff. I dont see anything special in the
factory, so it may be a ctor funny.

What I will do now is just set some breakpoints on Element.java:1185
in that test case, and just see how many times it crops up. That'll
show me what is going on.
