Support using reducers on JDK 6 without jsr166y?

[Stuart Sierra]

In Clojure-1.5.0-RC1, you can't load 'clojure.core.reducers without having either JDK 7 or jsr166y. But parts of reducers are potentially useful even without ForkJoin.

Is it possible to support reducers (and non-parallel "fold") when ForkJoin is not available?

The comments Rich added when closing CLJ-1109 indicate that this is definitely possible, and he would prefer it over the approach in CLJ-1109's patch, which was to throw an exception if no ForkJoin library is available.
