I start learning TW to use as personal wiki notebook. Potentially, I would 
have more than 250k tiddlers over time. So, I need to know the answer to 
this question. But, first, is it possible to open and save time to be that 
long as long as we are saving and opening a few tiddlers at a time? Also, 
Nick, are you opening and editing tiddlers in bulk or a few?
