  98 # In order to achieve these predictable offsets, all of the following tests
  99 # use speed=65536. Each job will perform exactly one iteration before it has
 100 # to sleep at least for a second, which is plenty of time for the 'quit' QMP
 101 # command to be received (after receiving the command, the rest runs
 102 # synchronously, so jobs can arbitrarily continue or complete).

 104 # The buffer size for commit and streaming is 512k (waiting for 8 seconds after
 105 # the first request), for active commit and mirror it's large enough to cover
 106 # the full 4M, and for backup it's the qcow2 cluster size, which we know is
 107 # 64k. As all of these are at least as large as the speed, we are sure that the
 108 # offset advances exactly once before qemu exits.
