A version that only adds to unique keys in the hash table, relying on the HASH-TABLE-COUNT value to indicate successful update.  The keys are the squares of the first eight primes, so the total threads spawned is eight.  the parameter to RUN now indicates how many squares of the given prime basis. But  still weirdness, in that the first thread which should increment the keys of the hashtable indexed by the powers of 2 doesn't seem to execute.  Something in my LOOP clause?
