I've instrumented proced-tests.el on emba. There was a failing
proced-refine-with-update-test. The *Proced* has shown the contents

That is, the first process is the parent of the second process, and the
second process is the parent of the third process. However, the test
assumes, that the first process is the parent of all following
processes

Does this information helps? Do you need more instrumentation on emba?

>> Thanks, Laurence

Best regards, Michael.
