================
Comment at: lldb/include/lldb/Core/Communication.h:86-89
+  lldb_private::Connection *GetConnection() {
+    std::shared_lock guard(m_connection_mutex);
+    return m_connection_sp.get();
+  }
----------------
This isn't necessarily introduced by your patch, but I don't think this lock does much other than make sure nobody can change `m_connection_sp` in between you calling `GetConnection` and you actually receiving the `Connection` pointer. It still comes with all the pitfalls of handing out a raw pointer (instead of a `shared_ptr`).

As a follow-up or maybe even precursor, we should probably stop handing out the raw connection pointer...
