This is rather simple on general *NIX. But:

1) it should be implemented for MS-Windows and OSX too if we really need this;
2) Linux has prlimit to tweak limits of another process at run time,
    so actual limit should be checked each time eval_sub is called, thus
    introducing a (minor?) slowdown.
