Whoops, sorry.

I think only someone here (zsh-workers) will add a new resource, and
I believe they will run the tests (but not sure they use
 --enable-zsh-debug). So just adding a test is sufficient, I think.

# Typical use of DPUTS() is to find a not-easy-to-find bug (corner cases
# etc.) which can be detected only by running zsh under various situations.
# Duplicated option letter should/can be detected more earlier.

As for the test:

So what the fix for this? Is it enough to skip the tests if loading
rlimits module fails (because we are testing module features, not
module loading)?
