I realise this, however this isn't a game, it's a BASIC interpreter. There
are times when the user is doing screen editing for example that he needs to
see the cursor movement for *every* keypress. It makes the logic
complicated, I try to work out how interactive the current situation is and
adjust the update/flush accordingly.

It is well known that Discworld trolls loose intelligence as they warm up.
Does this mean that a particularly hot headed troll would be a lava lout?
