+/* Trampolines
+ *
+ * Trampolines were an intent to speed up calling the same Scheme procedure many
+ * times from C.
+ *
+ * However, this was the wrong thing to optimize; if you really know what you're
+ * calling, call its function directly, otherwise you're in Scheme-land, and we
+ * have many better tricks there (inlining, for example, which can remove the
+ * need for closures and free variables).
+ *
+ * Also, in the normal debugging case, trampolines were being computed but not
+ * used. Silliness.
