This fixes rstudio/rstudio#6692 and rstudio/rstudio#1997.
I think what happens is that
select()returns immediatelyEINVALinstead of waiting when timeout is not “normalized”. I can’t find a canonical reference that this is required but for example https://www.gnu.org/software/libc/manual/html_node/Time-Types.html says:It seems that the problem was diagnosed 3 years ago, not sure why it wasn't reported in R.
