block_thread()

static void block_thread ( void *  lock_ )

static

Checks that recent_cpu and priorities are updated for blocked threads.

The main thread sleeps for 25 seconds, spins for 5 seconds, then releases a lock. The "block" thread spins for 20 seconds then attempts to acquire the lock, which will block for 10 seconds (until the main thread releases it). If recent_cpu decays properly while the "block" thread sleeps, then the block thread should be immediately scheduled when the main thread releases the lock.
