Note for the future, Kokkos 4.2 is now enabling asynchronous Cuda Malloc by default. This can be a problem for old UCX being used in MPI libraries (in particular on our test machine). Hence, we now disable explicitely this option in the test suite. However, I'd prefer not to disable this by default for production runs as it leads to performance improvement. I've added an item in the FAQ so that users see where the problem is if they run into this bug.
