Thanks Dirk. I agree. data.table is not in a situation to update very soon, so the easiest solution for the R community would be for CRAN to set OMP_THREAD_LIMIT to 2 on the Windows and Debian machines doing this test. Otherwise the 1400+ packages with hard dependencies on data.table will each have to implement custom logic to limit threads to 2. Toby
