Hi folks!

I'm using directors in my Ruby SWIG project to allow C++ code to call back in to Ruby. I have an interface defined like so:
%feature("director") IHostEventHandler;

In Ruby, I instantiate a class that derives from IHostEventHandler and then pass that to my C++ code via a SWIGified function.

For testing purposes, when the IHostEventHandler is registered, I create a C++ thread which calls one of the methods on the IHostEventHandler interface every 2 seconds.

The call correctly comes in to Ruby. However, once the call returns, the Ruby VM appears to be in a funky state and I'm no longer able to execute other commands on the console. Interestingly, the C++ code is still able to call in to Ruby via the interface; it's just like everything else in the Ruby VM has stopped working.

Am I misunderstanding how directors work in Ruby? Is it perhaps wrong for me to execute the callback on a non-Ruby thread?

Any help greatly appreciated,
Soren
