WaitAll[expr] waits for all concurrent evaluations represented by EvaluationObject expressions in expr to finish, then returns the resulting expression obtained.

For[start, test, incr, body] executes start, then repeatedly evaluates body and incr until test fails to give True.

WaitNext[{eid_1, eid_2, ...}] waits until the first evaluation represented by any of the eid_i finishes, then returns its result, the corresponding eid_i, and the list of ...
