How would you propose to avoid letting users exhaust system resources
without limits of some sort?  Sadly the real world implementations of
turing machines don't generally include unlimited tape...

Modest default limits are a good thing, since they help reduce the
impact of runaways, leaks and, indeed, DoS attempts.  This is as true in
*ix as it is in any other system.
