You also shouldn't expect that the "process stopped" output will contain the name of the process. That really is the name of the thread -- it just happens that on linux the main thread gets the name of the process. On macos for instance, this output doesn't contain the name of the process, even for the main thread:
```
(lldb) Process 6668 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP
    frame #0: 0x0000000185cf1b6c libsystem_kernel.dylib`__read_nocancel + 8
```
