There surely are problems in the JS garbage collector.
The example code attached also leaks a lot.
The KDE3 kjs/khtms seems to be much better (particularly the js engine)
although it is quite a bit larger. My sample code works well in KDE3, too.
I tried backporting just the garbage collector, but it's not easily doable,
since the problem seem to be related to the object model of the Javascript
engine rather than the garbage collector itself.
