core dumps

4.1 will also not dump core if the file "core" is not a regular file (i.e.,
it is a device or directory or ...), or if it already existed before the
kernel tried to create it but belonged to somebody other than your current
real uid, or if you were running with your effective uid not equal to your
real uid (i.e., you were running a set uid program), or if the file has a
link count not equal to 1.  None of these ways are any easier than using
vlimit or making the core file not writable, but just for completeness...
