Public bug reported:
Use case:
Scan enough pages for your XUbuntu to start dumping memory into swap
Save as image files
What happens:
You first wait for the last pages to be swapped out and first pages converted
You then wait for the opposite thing
What would be significantly better:
You can write later pages first, using the fact that it is already in the
memory at the end
I believe that it can be done as easily as changing the line 224 in book.vala
from:
for (var i = 0; i < n_pages; i++)
to:
for (var i = n_pages; i >= ; --i)
But i cannot test it, being unable to compile
