ptrace & lldb process):

(lldb) quit
Quitting LLDB will kill one or more processes. Do you really want to proceed:

Process::SetPrivateState (exited)
Process::SetPrivateState (exited) stop_id = 5
Process::ControlPrivateStateThread (signal = 1)
Sending control event of type: 1.
Process::ShouldBroadcastEvent (0x808cdee20) => new state: exited, last
broadcast state: exited - YES
Process::HandlePrivateEvent (pid = 74686) broadcasting new state exited (old
state stopped) to public
Process::RunPrivateStateThread (arg = 0x808aed500, pid = 74686) about to exit
with internal state exited...
Process::RunPrivateStateThread (arg = 0x808aed500, pid = 74686) thread
exiting...
The control event killed the private state thread without having to cancel.

<pause here for a moment>

Went to stop the private state thread, but it was already invalid.
