[maemo-developers] Tips to optimize SDL aplication

[From: Michael Stepanov]

Thanks a lot, Tarani. I should read maemo docs more careful :) I found the
tip of using valgrind under scratchbox in the Maemo Debugging Guide.

BTW I watched a top during the application was working. It took up to 80% of
memory and about 20% of CPU at some point. So, I'm going to trace it using
valgrind.
