it could conceivably take a very long time to generate the terrain for the settings you have. here's a run down of how terrain generation works. mapgen starts by scattering 'seeds' on the map, which must be a certain distance apart, this is the first parameter of the tsize command. it keeps placing seeds until it determines that no more can be placed, which is determined by counting how many times it tries to put a seed on the map, when it has tried and failed enough times, it stops trying. it could take a very long time if every time it tries to place a seed, it gets to the point where it is just about to quit, and then it finds a good spot for a seed, so it starts trying to place another one, which almost doesnt get placed, but just manages to, etc. this is bound to happen with very large maps with relatively small tsize parameters, so i would advise increasing them. i will take a look at the code as well, but i think that if you increase the tsize parameters, you will be fine.
