Previously, the control program could proceed to halt the timer and enter the verification stage w/o guaranteeing the matrix was fully unloaded from the streams to shared memory. This caused verification to fail on single-threaded runs. This was not a problem in multi-threaded runs, presumably because the other threads would be free to finish these copies before the copy of the last block (which the control programs always waited for) happened.
