While trying to compile Java I can into situations where there was simply no virtual address space left for a 32-bit guest to take. For example when Java tried to allocate 1GB of heap.
Part of the problem is that we're starting to map things at 0x40000000. This is a bit high. Taking that number down would give us a lot of free virtual address space which means we'd be able to squeeze more stuff in.
