I'm wondering whether the runtime code is sufficient to implement 6.0 runtime error behavior for the strict modifier. As I understand the runtime change in this PR, it only catches the case for serialized parallel regions.
I think, runtime error termination should catch whenever requested nthreads < effective nthreads. It could also be the case due to max-active-levels-var, or exceeding the thread-limit. At the end, the reason doesn't really matter.


The error from the build bot is confusing without having more output available from the error case.
