Zwei-Instanzen-Test unabhängig von der Startzeit, Bot endet immer

Browse Source 
Die Uhr des Hosts wartet jetzt auf den Gast. So kann ein langsamer Start
des zweiten Prozesses die Takte bis zum Vergleich nicht mehr verbrauchen.
Der Bot endet auch dann, wenn er seinen Bericht nicht schreiben kann,
und überlebt den Test nie. Ein leeres --storage= führt ihn nicht mehr in
den Ordner des Spielers. Ein neuer Test prüft, dass der Bot ohne
schreibbaren Bericht mit Exit-Code 1 endet.
