When I write something like:
while (true) {
NSString *s = [[NSString alloc] initWithString:@"applejuice"];

Will s be garbage collected? If not, how can I make sure it does get
deallocated by garbage collection.
As written, it's academic, as your program will never proceed
beyond this point, and will eventually crash with an out of memory
error.
In Leopard, definitely.
In Snow Leopard, maybe not. It is a rather contrived test case, but
it is much more difficult to outrun the collector in Snow Leopard
than it was in Leopard.
Bill, I for one would like to hear a bit more about this. What has
changed in SL? Why would it ever be possible to outrun the
collector? If the limit of memory is being reached, can't it always
just do an immediate, synchronous collection before the call to +alloc
returns? I'd love to have a better understanding of what's going on
under the hood here...
