C++ app with two threads doing an endless printing loop

When I have more threads in an app and I call SBProcess::Stop, only the main
thread stops and the rest of the threads continue.

The description of SBThread::Suspend states: "LLDB currently supports process
centric debugging which means when any thread in a process stops, all other
threads are stopped.".

I attached a simple C++ app that spawns a thread with the pthread library. Both
the main and the second thread print a message and then sleep for a while, when
I stop the process with SBProcess::Stop, the main thread stops printing, but
the other thread keeps printing the message and it's property is_stopped
returns False.

Do I need to do anything else to stop the other threads? I don't know how I
could stop them, as they don't have a stop method (apart of SBThread::Suspend,
but that serves a different purpose as far as I know).

Here's a minimal code example that shows that only the main thread gets stopped
(it prints True, False instead of True, True).

import lldb
import os
import time

debugger = lldb.SBDebugger.Create()
debugger.SetAsync(True)
target = debugger.CreateTargetWithFileAndArch("./test", lldb.LLDB_ARCH_DEFAULT)
process = target.LaunchSimple([], [], os.getcwd())

time.sleep(3)  # ensure second thread is started

process.Stop()

for t in process:
    print(t.is_stopped)</pre>
