Subject: Test failed because these was no expected-output file, but always printed
X-Git-Tag: v2.2a3~399
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=02035bc68d99e291e4c41ea0ea17536bb4ea95b9;p=python

Test failed because these was no expected-output file, but always printed
to stdout.  Repaired by not printing at all except in verbose mode.

Made the test about 6x faster -- envelope analysis showed it took time
proportional to the square of the # of tasks.  Now it's linear.
