        As far as I know, most muds are single-threaded -- all LP servers that I
        know of are, and I think most Dikus are as well. Giving users threads
        does seem to be something that a lot of new mud servers do, though.

        Hmm? This would require *no* interprocess communication -- all the
        threads are in the same process. Load balancing between threads is only
        an issue if you have multiple CPUs (otherwise they're all sharing the same
        CPU anyways), and even then, it should be the OS's job to balance things
        out (e.g., running multiple low-usage threads on one CPU, while a
        high-usage thread might get its own CPU).

        I'm not sure what you mean by "players would have to be moved between
        threads." Players aren't *in* a thread -- they're data structures which
        belong to the process as a whole. Different threads would access those
        data structures, but that doesn't involve any "moving" of the data
        structures.
        
        From what you're saying, it sounds like you might not completely
        understand the difference between a thread and a process. In a threaded
        system, a process is the thing to which resources are granted -- thus, the
        process owns memory, file handles, and things like that. Multiple threads
        exist inside a process, each executing a different part of the code that
        the process owns. Any thread within the process can make use of any
        resource that the process controls -- thus, all the threads can access the
        process' memory, file handles, etc.
        
        No IPC has to take place, because there's only one process involved.
        Threads may have to coordinate with each other, and IPC techniques may be
        useful for that, but it's not IPC. Thread communication can generally be
        a lot more efficient than IPC can, since the threads can use the shared
        resources of the process to communicate with each other.
