One solution i've seen for this is to use dummy children for unloaded  
nodes.  When you go to populate them for real, replace the dummy with  
real data.

I believe that windows explorer does this, too -- if you've ever  
noticed that the "+" on an empty directory goes away after you try to  
open it; that suggests that it doesn't actually check that  
directory's children until you try to show them.

In the negative direction, this goes back more than twenty times the  
age of the universe, and so suffices. In the positive direction,  
whether this range is sufficient to represent all possible times  
depends on the ultimate fate of the universe, but it can be expected  
to postpone overflow long enough for such implementation limits to be  
abolished.
