[Mono-dev] Mono-Debugger: Multiple threads and SingleSteppingEngines?

I got debugging of multi-threaded applications to work in OS X, as in
supporting it on the backend. But what I don't quite get yet is how
multi-threaded applications should be handled and represented inside
the debugger. In ThreadManager.cs, there is a comment:
// For each application we're debugging, there is just one
// no matter how many threads the application has. The engine is
using one single
// event loop which is processing commands from the user and
events from all of
// the application's threads.
Somehow, it seems to me that this is not really the case. In
ProcessServant.ThreadCreated (which is called when a new thread is
created by the application):
SingleSteppingEngine new_thread = new SingleSteppingEngine (
manager, this, new_inferior, pid);
Seems to contradict that. Looking at the code, I assume the above
comment is wrong. It appears that the debugger will create one
SingleSteppingEngine plus Inferior for each thread. Am I right?
