Waiting for all the threads for completion may incur a noticeable delay when exiting in an error condition. Currently, when we exit from one thread running a parallel-for loop, I believe the entire process exit immediately, but if we wait for all thread to complete, I think we'll wait for the parallel-for loop to complete. That situation could happen if we are processing relocations, for example, and found a lot of relocation errors.
