If you just rm files you get the below result where coredumps are described as 
"missing", a proper solution would remove them from the list.

Also whatever the proper solution is deemed to be needs to be documented, the 
man page mentions nothing about this.

Among other things there should be a way of limiting disk space usage to avoid 
running out of free space from large core dumps.
