+// LocalDebugDelegate
+//
+// LocalDebugDelegate creates a connection between a ProcessWindows and the
+// debug driver. This serves to decouple ProcessWindows from the debug driver.
+// It would be possible to get a similar decoupling by just having
+// ProcessWindows implement this interface directly. There are two reasons why
+// we don't do this:
+//
+// 1) In the future when we add support for local debugging through LLGS, and we
+// go through the Native*Protocol interface, it is likely we will need the
+// additional flexibility provided by this sort of adapter pattern.
+// 2) LLDB holds a shared_ptr to the ProcessWindows, and our driver thread also
+// also needs access to it as well. To avoid a race condition, we want to
+// make sure that we're also holding onto a shared_ptr.
+// lldb_private::Process supports enable_shared_from_this, but that gives us
+// a ProcessSP (which is exactly what we are trying to decouple from the
+// driver), so this adapter serves as a way to transparently hold the
+// ProcessSP while still keeping it decoupled from the driver.
