That may be good enough. But GC will probably kick in right after we = set it back, so probably most methods we might try for measuring startup = time will incur the cost of at least one GC pass, and it=E2=80=99ll = happen when the user starts Emacs in real life. I guess one question = is, how much it matters? It=E2=80=99s only a fraction of a second, but = I=E2=80=99m trying to shave a startup time of 0.2s (or 0.6s on Mac OS X) = down closer to 0.1s, so a fraction of a second can make a difference.
