demonstration
I am finding I have to explicitly pass a launch policy to get async to run
anything in a thread. For example, when I time the attached with
-DFORCE_PARALLEL I get
/tmp/tst 81.54s user 0.23s system 628% cpu 13.001 total
and without it I get:
/tmp/tst 41.29s user 0.05s system 99% cpu 41.343 total
