And here we are at the last patch of this series.

Allow me to say that this is quite good a first contribution! Thanks
for this, and I'm looking forward to seeing version 2!! :-D

About this patch, a few comments below.

I think you can just initialize rc with EXIT_FAILURE, assign
EXIT_SUCCESS to it near the end, if everything went ok, and then keep
the 'return rc';

For this one: I've sent a patch for another reason yesterday, and while
there I did the exit code adjustment myself. So, update your tree and,
if my patch has been committed already, just skip this function.

Which brings up a question: what git tree are you using for
development? You should stay either on master or staging branches (and
I recommend staging) of the official repository:

Same as already said for main_cpupoolcreate, just us rc.
