We should make sure people know what they are used for. They were asked for by Stig because he wanted to be able to start opening http:// connections but continue some processing at the same time because opening a connection takes time. This still hasn't been implemented but it's one of the only real life examples ticks should be used. If it's not something special like this you're doing then don't use ticks.
I wanted to optimize things, because creating PNGs takes quite a while, during image creation I wanted to continue processing of
the whole page or even create another image(s) concurrently. I tried to figure out what´s the advance using ticks, I failed.
Found no plus the way I tried.
