Okay, I think I understand the challenge: you can't use lldb to synchronize
(e.g. by waiting on a `pause()`) because by attaching, you're already going to
be parsing the library. We have a few other tests that have this issue, and
they use a file to synchronize through `lldbutil.wait_for_file_on_target`.
```
# Use a file as a synchronization point between test and inferior.
pid_file_path = lldbutil.append_to_process_working_directory(
self, "pid_file_%d" % (int(time.time()))
)
self.addTearDownHook(
lambda: self.run_platform_command("rm %s" % (pid_file_path))
)
popen = self.spawnSubprocess(exe, [pid_file_path])
pid = lldbutil.wait_for_file_on_target(self, pid_file_path)
```
I think we could use the same approach here.
