Executing block of code without context switch?

No, there is no easy way to achieve that -executing a code without context switches- (except if your code is running inside the kernel, but you want to handle interrupts anyway).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
