Note that is *virtual* memory, i.e. address space. This is needed to maintain segregated heaps for different object types. It doesn't actually consume resident memory. I'm impressed the xapp developers made the app work on macOS. They weren't kidding about their apps being cross-desktop. Honestly, I didn't know that it was still possible to build WebKitGTK on macOS at all!
