Hi Eliot, 

Sorry for the delayed answer, I've been running with other issues :(
Yes, I think this is important and I would like to allocate some time to work on it. I will start preparing a CI-job for the CogMT, next step would be to finish your cases. 
If you point me where to start, I can be your collaborator in this task :)

Hi Eliot,

I've seen that you are consistently maintaining the MT version of the Cog, so I wonder what is his status.
Is it usable?

I have a very simple test case, a REPL loop that runs in parallel with the UI.  This works.  I had a more complex case that I have not maintained, a concurrent callout to the Mac file chooser dialog.  The dialog uses (asynchronous, concurrent) callbacks to ask the client about valid file names.  This nearly worked but I haven't had time to get back to it.  (Another unmaintained test case is a concurrent interface to ODBC).

I think the scheme should work well but it requires work.  I think the work is worth it, but I need to find the time, and I need a collaborator.

Esteban, I think this would be relevant for your Mac UI work, and would revolutionize the Squeak/Pharo FFI.  But it is not an easy thing to develop (concurrency is never easy to deal with).
