Description

testRateThrottling verifies that bootstrap transfer should timeout with a very small DFS_IMAGE_TRANSFER_BOOTSTRAP_STANDBY_RATE_KEY value. However, throttling on the image sender only happens after sending each IO buffer. Therefore, the test sometimes fails if the receiver receives the full fsimage (which is smaller than IO buffer size) before throttling begins.
