One thing to note, is that his problem is lack of contiguous VA space, not physical frames (i.e. "memory"). Killing services will do nada to help that, the only thing that will help is mapping less DLLs.
DLLs are loaded in a process address space only because they are referenced in the PE header or the process calls LoadLibrary(), I'm afraid killing processes won't cause mapping of less DLLs either.
