Season with black pepper. Saute for 30 seconds. Add the crispy bacon and the pasta. Add 1/2 cup of the reserved pasta water and cook until pasta is warmed through and coated with the bacon drippings. Season the eggs with salt and whisk in the cheese. Remove the pan from the heat and add half of the egg mixture, along with more of the pasta cooking water, and whisking quickly until the eggs thicken, but do not scramble. Add the remaining egg mixture, toss quickly and thoroughly until the pasta is coated with the sauce and the mixture thickens, adding more pasta cooking water if necessary.
