================
Comment at: lldb/source/Host/posix/MainLoopPosix.cpp:399-402
+  if (m_triggering)
+    return;
+  m_triggering = true;
+
----------------
Maybe something like `if (m_triggering.exchange(true)) return;` ?
This version should work as well, but it may save someone from wondering what will happen if two threads execute this concurrently.
