Allow a parallel context to relaunch workers. This may allow some callers to avoid the overhead involved in tearing down a parallel context and then setting up a new one, which means releasing the DSM and then allocating and populating a new one. I suspect we'll want to revise the Gather node to make use of this new capability, but even if not it may be useful elsewhere and requires very little additional code.
