In most modern OS's, the vm implementation will use copy-on-write so that only modified pages are copied. Also there are optimizations so that if you exec in a child process shortly after forking, the process will use minimal memory. If you stress the facility, you may encounter problems, but it should survive normal usage, assuming your system has enough memory available to handle the AOLserver image plus the ImageMagick image.
