2. Since there aren't a whole lot of 64-bit apps out there, when some users see them using more memory, they tend to think something's wrong with the app. This is especially true if GC is also turned on, as it is in 64-bit Xcode, and the VM requirement swells to 30+ GB. I don't remember why turning GC on does this.
The collector reserves a 32GB zone of addresses to serve up scanned allocations (the autozone).
It is only allocating addresses and not actually touching all of that memory. Thus, it bumps the address space by 32GB, but does not actually use 32 GB of memory or VM.
