strange fails in distributed, seems to be related to empty work on rank and termination detection

[therault]

Describe the bug

the strange test fails if run in distributed. There is no reason for this, it should run even if the work is located on a single node. Looking at the stacktrace it seems as if the termination detection does not handle the case where a taskpool is locally empty

To Reproduce

run strange in distributed

still an issue, will postpone to 4.1
