-     * These options control the zealousness of the GC. At every allocation,
-     * nextScheduled is decremented. When it reaches zero we do a full GC.
-     *
-     * At this point, if zeal_ is one of the types that trigger periodic
-     * collection, then nextScheduled is reset to the value of zealFrequency.
-     * Otherwise, no additional GCs take place.
-     *
-     * You can control these values in several ways:
-     *   - Set the JS_GC_ZEAL environment variable
-     *   - Call gczeal() or schedulegc() from inside shell-executed JS code
-     *     (see the help for details)
-     *
-     * If gcZeal_ == 1 then we perform GCs in select places (during MaybeGC and
-     * whenever a GC poke happens). This option is mainly useful to embedders.
-     *
-     * We use zeal_ == 4 to enable write barrier verification. See the comment
-     * in jsgc.cpp for more information about this.
-     *
-     * zeal_ values from 8 to 10 periodically run different types of
-     * incremental GC.
-     *
-     * zeal_ value 14 performs periodic shrinking collections.
