I've recently been doing some experimentation with computed gotos in an
unrelated program, and I've also observed a slowdown in most cases.  This
indicates to me that gcc typically does a fine job of optimizing switch
statements, and there isn't a whole lot to be gained by second guessing it
in such cases.
