Summary: Changes for Suns

Peter's go referee doesn't run on 2.x Suns because of his child timing
hack (for which he he predicts a day in hell for himself, of which this
posting is possibly the first minute).

(The second minute is the following: you must mkdir SUBS and GREF
before sh'ing his file.)

Here is the contextual diff that makes the program run on Suns, while
unfortunately breaking the child forking cheating check.
