Yepp. It was to show my intention.

In the patch, every dump got its pid attached.

But then, you won't eliminate the find and make automatic removal even

Ah, I c. *.core would be ok.

I don't really like that, but why not. Setting the directory via
sysctl is in every case superior to defining it at compile time.
You will at least have some unique pattern in the name (that the 
kernel should probably add) to make automatic removal possible. Users
tend to waste much disk space by not removing core dumps.
