Hi Nicolas.
Do we really want to keep this kind of test?
Such benchmarks (and benchmark-like tests) should at least average over several runs and only fail as a test if something actually got slower on average. Or something like that. A single misbehaving run should not be the reason for such a test failure.
Maybe we can tweak #should:notTakeMoreThan: to evaluate the block several times? But then it cannot fail early on as it is doing now ... Hmmm...

Hi all, sometimes, some build fail for just 1 test...

4ms, really? On C.I. infrastructure, anything can happen... Do we really want to keep this kind of test? We eventually could once startup performance is known (see isLowerPerformance discussion on squeak-dev), but in the interim, I suggest we neutralize this specific test in Smalltalk-CI.
