Summary
The idea is shamlessly taken from apache/datafusion#21084, which improved CI runtimes there significantly (and also makes a real difference in performance).
Fetching the available parallelism isn't free, both because it might generate a stack trace and because it might end up doing a bunch of work, its even called out in its docs.
