From: Kunwu Chan <[email protected]> The test aborts if the initial aggregation cycles produce zero tried regions. This can happen on slow machines, causing false failures. Skip empty cycles and retry up to 200 times before giving up. Also check that enough samples were collected before computing the 50th percentile.
