I think that, I found root of my problem.
As far as I have million nodes under few nodes, there is maintained 
TDOMNodeList, which stores nodes in TFPList
As new nodes are appended TFPList.Expand is called
And there is:
   if FCapacity > 127 then Inc(IncSize, FCapacity shr 2);

So if I have in list 1 000 000 items, then at once list is expanded by 
250 000, which causes in one step out of memory
So my question is: can I somehow control increment count ? I think that 
ATM no.
So second question is can TFPList.Expand be modified, that for large 
FCapacity will be used smaller increment ? :-)
