WebBuffer pairs: Sentinels Objective : Optimize the common case by reducing the number of tests to one per advance of fwd. Idea : Extend each buffer half to hold a sentinel at the end. This is a special character that cannot occur in a program (e.g., EOF). It signals the need for some special action (fill other buffer-half, or terminate processing).
