Prime lags after extensive processing

[Angus]

To make clear - I can follow your argumentation. Sometimes I am slow, but I am not a plain idiot ;-) It just seems to be not the best way to go. Introducing problems for you, the developers aswell as for the user. It is a pity to imagine the second or third best solution was chosen.

Ok thought market-wise students could be advised to buy the prime because no harm is done if used like a 38. Maybe that was also an argument besides given code you had to extend.
