I guess the -client version is the default, and that is what I used.

I was positively surprised by the Erlang performance of ~60ms
for the nrev example and for() implementation I used. GNU
Prolog does it in around ~250ms with for backtracking.

Didn't check YAP Prolog, but I
guess it will do it in around ~25ms.

But the Java performance also surprised me. Especially since
the code contains many new expressions. But rumors have
it that new is just a pointer decrement in Java.
