Cannot set concurrency below the number of workers defined

[dobesv]

When specifying a concurrency limit, I might get this error:

Error: Could not adjust maxWorkers per task to fit the concurrency, try reducing the maxWorkers, or increasing the --concurrency CLI argument, or separate the tasks to be run

It seems like an unnecessary limitation that I must have enough concurrency for every worker to be running one task in parallel. Surely workers could just be left idle to enforce the concurrency specified even if it is less than the specified concurrency?

After some digging I found that actually this may be that you cannot set concurrency lower that the number of workers that will be used by the target you are running, and which also specify an explicit maxWorkers value.
