100% agree with you, and that's what i would normally do. But
unfortunately, this time i must wait in the mainthread for the
callback. I know it's wrong, but this time i've gotta do it.
Then use a while loop to run the runloop until your callback's been
invoked. The reason this is described as wrong is because it blocks
the main thread; but if you have to block the main thread, this is
the way to do it.
Excellent. I remember reading somewhere that because of changes in
10.6 to the way the runLoop works, it was a bad idea to do this. But
for now its working and until someone tells me otherwise, this'll do.
thx
