[Twisted-Python] Object prevalence (advogato article)

http://advogato.org/article/398.html 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 :) -- tv@{{hq.yok.utu,havoc,gaeshido}.fi,{debian,wanderer}.org,stonesoft.com} double a,b=4,c;main(){for(;++a<2e6;c-=(b=-b)/a++);printf("%f\n",c);}
