Usually a bug fix always includes a NEWS entry, at least to indicate that a crash has been fixed. In this case, it's a data race that has been fixed when an exception is being copied while being mutated. |

Adds a critical section to prevent a data race in
exceptions.c.Unsure if the test is in the right location.
I don't think that a news entry is necessary.
