0 and 1 is probably too small, and will result in extra arraycopy operations.
Eventually I'll have to add some real tests. For children I'm starting with a capacity of 1, since that's what will be needed for the very <common>case</common> of an element that only contains text. When I get some real benchmarks I can adjust this.
So far I haven't been able to get my memory down enough to run the programs I want to run. This is with heap sizes of up to 768M which is absolutely obscene for the size of the documents I'm processing. I suspect a memory leak somewhere.
I'm investigating profiling tools to help me locate it. So far I've discovered JProbe is completely non-functional. Once I find something that actually works I may be able to track this down.
