[Vm-dev] Re: [Pharo-dev] Alien and FFI in Pharo

[Robert Withers]

I just had a realization. I do need MT (is this what forking 
callout/callback threaded vm is called?) I think, for callout, not 
callback. The select call is a blocking call and will block the image 
thread. Is it true?

If so, let's figure it out, Craig. I'm with you.

thanks,
Robert
