{code}
blockUntilNoRIT() has these calls:
{code}
ZKAssign.blockUntilNoRIT(zkw);
master.assignmentManager.waitUntilNoRegionsInTransition(60000);
{code}
We can see that master.assignmentManager.waitUntilNoRegionsInTransition()
waited at most 100 ms, far shorter than 60sec limit.
Should we wait longer ? I think using NoRIT criterion alone isn't enough.
