The question is: What is a good default for things such as @parallel when SAGE_NUM_THREADS has not been set? I think that 1 is not a good one. The actual number of cores/threads on a system probably isn't either on servers with lots of cores. At some point we had `min(8, number of threads)` which appears reasonable to me.
I would suppose that by default Sage uses all cores (or one core); all other limits are artificial.
(But Sage doc should contain a little page telling how to use timeout, taskset and ulimit commands on some common Linux distribution. Maybe also a link to page telling about cgroups and even about at-command.)
