In Mac OS X 10.5.8, using fullscreen with L4D2 will often cause crashes or extremely slow performance. This might be how Quartz (the engine Mac OS X uses to render graphics) handles fullscreen applications.
Switching to windowed mode shows a HUGE increase in performance. Also, dropping resolution will improve performance, which applies to most every fullscreen app or game.
