Amazing. I tried the AVLTree used by fpspreadsheet and it needs 0.37 sec
for 1000x1000 and 10.3 sec for 5000x5000.
My tests were all "in memory", no disk access whatsoever.

Mine as well.
I would be tempted to implement such a table in fpspreadsheet, but its
problem is that it occupies memory for empty cells while the AVLTree
stores only existing cells (at the expense of the cell record which
contains row and column indexes).
