Log message:
	2006-03-26  Martin Hunt  <hunt@redhat.com>
	
	* bench2/bench.rb (Bench::run): Instead of loading the module
	once and running against different numbers of threads, load
	and unload the module each time. Then keep track of failures
	per thread. Also use the new itest to keep the tests the same
	size regardless of the number of threads.
	(Bench::initialize): Make itest if needed.
	(Bench::load, Stapbench::load): Increase buffer size to 8MB.
	
	* bench2/itest.c: Change arg to be the number of threads
	instead of the number of millions of calls to make.
	This makes it easy to divide the work among multiple threads
	without making the test run many times longer.
