Yes, this is consistent with what I can see on 2.6.25-rc3 (which I still
had lying around on the test host):

glass:~/ptrace-wrong-notify # ./task_ptrace_attach ./forktest 10 10
creating 10 additional process(es)
10 iterations
pid006 errno=0 exited=0 stopped=1 signaled=0 stopsig\x19
SIGSTOP from [3006]
pid006 errno=0 exited=1 stopped=0 signaled=0 stopsig=0
EXITED [3006]
pid005 errno=0 exited=0 stopped=1 signaled=0 stopsig=5
FORK new_pid [3006]

and so on... Ok, I'm going to play with git now. ;]
