So they are above 4GB already. There is unfortunately no cross-linker in MSVC, so you can't link 32-bit binaries with a 64-bit toolchain. We're in the process of switching to 64-bits OS with a 32-its toolchain, which will allow an extra gigabyte of address-space. We've gone past the current 3GB limit a couple times now, at which point, we moved some stuff out of libxul. Before that, we hit the 2GB limit, at which point we used the /3GB option that allows for the extra GB.
