Test 2: Get task 0 to get buffers 0 -> 4 from the pool hold them. Then get task 1 and task 2 to get them with blocking. The 2 tasks tests the priority blocking on the buffer. Test 3: Read a block from disk into the buffer, modify the block and release it modified. Use a block great then 4 because 0 -> 4 are in the cache. Test 4: Read every buffer in the pool and hold. Then get task 1 to ask for another buffer that is being accessed. It will block waiting for it to appear. Test 5: Read every buffer in the pool and hold. Then get task 1 to ask for a new buffer. It will block waiting for one to appear. Test 6: Get 5 buffers, release modify 4 then sync the last. Test 7: Get 5 buffers, release modify them all then sync the device. Test 8: Get 5 buffers, release modify the last 2 then the reset from 0. TODO: if possible, break into separate tests
