commit fe92a91f1e713ba4951bc6e6162f8803dc76b816

    Reduce benchtests time
    
    Reduce the total time taken by benchtests.  The malloc thread test takes 4
    minutes to run which is significantly more than most other tests. Reduce
    this to a more reasonable 40 seconds.  The math tests take 10 seconds each,
    eventhough all they do is loop on the same input.  Anything more than 1
    second runtime is way overkill, so set the limit to 1 second.
    
    	* benchtests/Makefile (BENCH_DURATION): Set to 1 second.
    	* benchtests/bench-malloc-thread.c (BENCH_DURATION): Set to 10 seconds.
