The longer the tests take, the fewer times they can be cycled.

That is a particular problem as a release nears. The release manager often
has to delay some action pending the outcome of tests. Not a problem if the
tests run quickly and cycle often. But when a test cycle takes 2 1/2 to 3
hours, as was common during the runup for 1.31.0, it adds days to the time
it takes to finish a release.
