max_concurrent_checks=0 not working on 3.2.1 (maybe earlier versions, too)?

I'll add it to our git repository once I've integrated it into Nagios.
For now it's just a simple stand-alone program that spawns and reaps
2000 small checks as fast as it can. You should be able to get it from
git://git.op5.org/nagios.git if you checkout the dev branch (once it's
in, ofcourse).

It's worth trying already though. There's lots of bugfixes and code
cleanups in there now.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
