FWIW, I tried your original example on Linux yesterday, and it seemed to
work fine --- it only wanted to use 1 worker, but the speedup was just
about exactly 2X with or without "explain analyze". So this is somehow
Windows specific. That's darn odd; in a quick look at the relevant code
I see nothing that looks platform dependent.
Somebody will need to trace through this on Windows and see where it's
going off the rails.
