True or False: when USE_OPENMP=1 is not used, then race conditions are not unexpected. If True, and we wish to avoid race conditions, then sources such as the conda channel and ubuntu would need to add this enhancement. If False, then what is the next step (i.e. forum) for debugging the race

I’m not really familiar with conda, but if they’re being packaged together then an omp build might be more appropriate. Perhaps another point for Juan’s list: whether OpenBLAS is the right choice to pair with. The library itself hasn’t produced optimized kernels for any of the Intel *Lake chip

As things stand now, package tarballs with vignettes that are built with R-devel will not install in R 3.4.x, so CRAN can't accept them and someone running R CMD check --as-cran should be told that. A WARNING is appropriate. Most likely what will change soon is that build/version.rds will be save

This change poses difficulties for automated build systems such as travis-ci, which is widely used in the R community. In particular because this is a WARNING and not a NOTE this causes all R-devel builds with vignettes to fail, as the default settings fail the build if R CMD check issues a WARNING
