The problem with all of this is that all the different plugins that 
expect different SIGCHLD behaviour are running in the same process and 
you can only have one behaviour for all of them. I encountered that with 
the Python plugin years ago, documented in the collectd-python man page. 
That's why 
https://github.com/collectd/collectd/blob/master/contrib/python/getsigchld.py 
exists. Note the warning about it breaking the exec plugin because it 
has different expectations. I'm not sure if there is any good solution 
for this problem.
