The design of core dump handling in Linux leaves much to be desired. Among its several flaws, the biggest is that it is a global setting, accessible only by the root user. A proper design would either allow it to be isolated via namespace, or delegated to a reaper/subreaper process (in an opt-in fashion for back-compat). There has been discussion of the former idea [0] and even a submitted patch [1], but it seems like it never went anywhere.
