Comment 11 for bug 1604446

Last known position is almost always going to be a full house level GPS lock on the place where you last turned off a map application, probably the last destination you navigated to. Might also be a full GPS lock on the last place you took a photograph. This could be a problem for implementing things like http://pooperapp.com/ on Ubuntu Touch ;)
As long as getCurrentPosition doesn't just return LKP and calls startupdates() and returns the first position from that (I am a little unconvinced it calls startupdates at all, because then repeated calls would presumably eventually work and they don't?)
