parsl-visualize reports large number of workers in resource usage graph

[benclifford]

Describe the bug

See the attached screenshot from running pytest --config parsl/tests/configs/htex_local_alternate.py

The plot shows 6000 workers. This seems wrong - I would expect around 8 (cores) * 5 (blocks) in my laptop test environment.

To Reproduce

pytest --config parsl/tests/configs/htex_local_alternate.py

parsl-visualize on the resulting monitoring.db in pytest-parsl

Expected behavior
Something more like the expected number of workers (perhaps more like max_blocks * number of cores? which would be 40 on my laptop)

Environment
my laptop

Distributed Environment
my laptop
