This phenomenon has gone away today. Building is OK on Mac.
Also "validate" resulted in:
codeGen/should_run cgrun071 [bad exit code] (normal)
perf/compiler T4801 [stat too good] (normal)
perf/haddock haddock.Cabal [stat not good enough] (normal)
perf/haddock haddock.base [stat not good enough] (normal)
> Hi all,
>> I've merged the new parallel I/O manager that Andreas Voellmy and Kazu

>> linearly up to 32 cores I believe. Perhaps Andreas could post the numbers.
