[R] stopping functions with long execution times

[Henrik Bengtsson]

See evalWithTimeout() of R.utils, e.g.

tryCatch({
  evalWithTimeout({
    slowFunction();
  }, timeout=7*24*3600);
}, TimeoutException=function(ex) {
  cat("Timeout. Skipping.\n");
})

help("evalWithTimeout") have more information and cross links.

Currently I have an INLA model running for 35 days and still no results. The process still uses near 100% of the CPU and less than 1 GB RAM on virtual Ubuntu box with 8 GB RAM on a blade server.

E.g. let the model run but kill it automatically once it runs for more than 7 days. Once killed the model should throw an error so we can catch that in the error-handling.
