I didn't look at what exactly the patch does, but on first testing it
reduced the running time from 9000+ milliseconds to 250ms. So that's
definitely a step in the right direction. I also replaced the hard-coded
text being added to the memo with "line <n>" where n is the value of the
loop variable to confirm all lines have been added. They were.

I tested with Lazarus 1.7 r52919 FPC 2.6.4 x86_64-freebsd-gtk 2.
