Possibly not known to me :)

Do you use scheduling contexts? If not, I'm not aware of an issue, would
you have a small reproducer?

Normally it does, we check this in the CI by running the output through
pjdump.

Without precise reports, we can't fix bugs :)

There is no such support, but such a feature would be very welcome
indeed.

Normally they would be documented in the offline performance feedback of
the StarPU manual.
