The stress test possibly uses multiple pthreads. MPI collectives are possibly not correctly matched. Not sure if this is fixable...

One idea would be to use an own communicator for all threads, but I don't know if this is possible...

Might using MPI_Init_thread help here? Just guessing, we need to investigate.
