Review comment:
I remember not long ago, we had to change a few nanoTime operations to avoid
overflow.
I think, based on that the correct would be System.nanoTime() - timeout > 0
There was a previous big commit where we changed a few like this... the
commit I could find where Franz changed something similar was
35c3475092576e7b008220f7c39b78e15850d5fd
Can you make that change here please?
