So for now I will just skip those three bad boys. Two of them, as I recall, are merely unreasonable and finish after a while. The other way ran all night. I'd love to know how CRAN deals with that, or understand better why it doesn't bite me on the server at home.
CRAN has different approaches. Under Windows, I typically have an R process that controls the check process and writes out the process id and timestamp and then starts R CMD check. Another watcher simply kills the process of a given process ID including all childs if they are beyond some timeout threshold. Best, Uwe
