Thanks for this pointer. The main trick for unix is done in kinit/kinit.cpp

        fprintf(stderr, "kdeinit4: Suspending process\n"
                        "kdeinit4: 'gdb kdeinit4 %d' to debug\n"
                        "kdeinit4: 'kill -SIGCONT %d' to continue\n",
                        getpid(), getpid());
        kill(getpid(), SIGSTOP);

The real question is how to suspend the process so that gdb or other 
debuggers can continue the attached process.
