I think this is more like "catch fork" and "catch syscall fork clone".
ptrace already offers PTRACE_O_TRACEEXIT so we could be using that even
when "catch syscall" is not fully functional on the target (i.e.,
there's no XML file to translate syscalls names to numbers).  But Tom
may correct me here.
