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.
