How much memory is used here, do you have an estimate? (I'm aware file size 
and complexity matters here...)

Perhaps rather than implementing a disk cache, you could have an option to 
store the node tree in memory and let the os swap engine take care of disk 
cacheing if needed?

Personally, I usually have only five or six files open, so i doubt it would be 
an issue for me...

Or perhaps keep the latest X node trees in memory, since even if you have many 
files open, you usually work on a few at a time (me, that is ;)

By default then, you'd set X to 1 and you'd have the current behaviour. People 
with too much memory could increase the setting.
