stub run local & on github actions hangs indefinitely

[kelly-sovacool]

The stub run hangs after completion -- nextflow doesn't recognize the processes are all done. This happens on github actions and locally. Doesn't happen on biowulf with lots of memory.

cd tests/cli
champagne init
champagne run -stub -c ci_stub.config --max_cpus 2 --max_memory 6.GB
