This introduces simpler execute permission check in check.executable().
Because writing-and-then-deleting the transient syslog.txt file can possibly trigger race condition during parallel R sessions.
We recently faced this error when running FLa4a in parallel (using forceach - %dopar%):
Error in e$fun(obj, substitute(ex), parent.frame(), e$data) :
