Ok, if I get the vm-dev mailing list correct then in fact people can see the note, since vm-dev@discuss.squeakfoundation.org (old) bounces it back

Ok, a few years back we managed to add in the following logic from Andreas, however it was not exposed by sqVirtualMachine.h
now do we want to remove it? Or leave in place.
If this is replaced by Alien what's the magic equivalent for doing the callbackEnter and callbackLeave since I"m doing that in the Objective-C squeak proxy logic.
/* New methods for proxy version 1.? */
/* callbackEnter: Re-enter the interpreter loop for a callback. Arguments: callbackID: Pointer to a location receiving the callback ID used in callbackLeave Returns: True if successful, false otherwise */ sqInt (*callbackEnter)(sqInt *callbackID);
/* callbackLeave: Leave the interpreter from a previous callback Arguments: callbackID: The ID of the callback received from callbackEnter() Returns: True if succcessful, false otherwise. */ sqInt (*callbackLeave)(sqInt callbackID);
/* addGCRoot: Add a variable location to the garbage collector. The contents of the variable location will be updated accordingly. Arguments: varLoc: Pointer to the variable location Returns: True if successful, false otherwise. */ sqInt (*addGCRoot)(sqInt *varLoc);
/* removeGCRoot: Remove a variable location from the garbage collector. Arguments: varLoc: Pointer to the variable location Returns: True if successful, false otherwise. */ sqInt (*removeGCRoot)(sqInt *varLoc);
