That looks not bad in my eyes. Well, i'm not sure if it right but i don't send a
ponder move if this feature is enabled. That makes no sense for me. I allso
expect this command as "false" state if homer leave the analyze mode.
But of course thats only my own thoughts. Maybe dieter could make it more
clearer...

I'll just looked in my source what happend with a newgame command:
if (!strcmp(command, "ucinewgame")) {
NewGame();
InitHashTable();
continue;
}
I'll reset all things.
A bigger problem is more the handling "set option <x>" while engine thinking:
Fritz8: Make it without any changes.
Arena: Allow it in some special cases (clear hash for example)
S9: Send even a "stop" before the command.
This shows us here is may a unclear state..
