Short summary:
-keep all state in RAM, no traditional database.
-write snapshots of state to file every n hours.
-write a journal of all commands coming in to journal.
-in case of crash, restore state+rerun journal.
This is pretty close to what Python and Twisted .taps can do.
Let's have a goal of being able to do it all, easily.
I think I'll add .tap rewriting every n seconds to MC Foo now :)

double a,b=4,c;main(){for(;++a<2e6;c-=(b=-b)/a++);printf("%f\n",c);}
