Who is the maintainer of the FFI-Package for Squeak and/or Pharo ?
I guess I'm the de facto maintainer because I'm the one who has changed things most recently, reimplementing the FFI plugin via the ThreadedFFIPlugin.
I especially interested in the FFI-Unix examples and the state on working FFI on linux for current squeak release (AFAIK it does not work with "squeak all in one" 4.5)
Can you give me a reproducible case? I'd this with a Cog,Stack or Interpreter VM? Which specific things fail and how?

The last package comment from Name: FFI-Unix-mtf.4 Author: mtf is "made the XLib examples actually work (Window is an unsigned int handle, not a struct)" That the window is an int handle and not a struct explains why this version replaces the parent class of XDrawable from ExternalStructur to Object. But all calls with an XDrawable still have this object as parameter ( and not its instance var "xid"). I don't understand how this ever worked (or was there some kind of automatic argument conversion like: transform an object with an instvar -> a int, if the function expects an int handle?) Sure we can replace all XDrawable arguments in X11 calls from "aXDrawable" to "aXDrawable xid". But I only wonder, did this ever work and if Author "mtf" did the last change, can I contact him or is he still maintaining the FF-Unix examples?
