------------------------------------------
Scott,
I tested your patch on various workloads and there was about 10% performance
hit on larger documents (~300kb). I, however, was able to eliminate this
slowdown by doubling InitialHeapAllocSize and MaxHeapAllocSize. Will it still
be acceptable to you (i.e., the smallest DOM document will use 16Kb of memory)?
