Let me know your design...
This patch does using fork+execve() rather than calling UMH in pipe-coredump pass.
And coredump-pipe process is run as a child of get-dumped process.
Doesn't this break existing solution actually used in distro ?
BTW, it's first time for me to see that _do_fork() is called outside from fork.c.
Isn't it better to add a new func in fork.c if we really need this ?
