Re: Recovering partial factorizations when using trap() and alarm() to abort factorint()

Thanks again Max!

I saw that this was part of the code you posted but I didn't try it as I thought it was doing something completely different. If you're doing lots of factoring then factor(N,0) will presumably slow down a lot as the list of stored factors grows... I think I'm catching on to the way things are done round here... I presume if I change primelimit then the stored factors are forgotten and the memory is freed?
