Not at all ! If server do not control how much resources program try to use,
its
absolutely
easy to hang up it. Just try to create new child processes in loop, and after
few seconds and 900-1000 created processes, your'll loose control over system.
No console, no ps, forget about keyboard and terminal.
But this can be done with program at any language in Unix-like OS.
Just "To Teach" my provider i did that approx. 4 times per day in almoust
week.
They just reboot system over and over. I have to call to "Admin" and
tell him what to do.
But at properly configured server with good admin its not possible.
