--single-process command line not working

The --single-process (command line) does not work. Can this be fixed? All Chromium browsers, Dragon included, are heavy memory users, and not everyone has 4+ GB of memory lying around. I’ve recently often heard the saying “memory is cheap”, but if you’re on an older computer (say, one that uses DDR1 or DDR2, or one that’s motherboard severely limits the memory), then simply buying more memory may not be an option. I’m aware of the --memory-model=low switch, but even with that, Chromium browsers still hog the memory.
