Hi Paolo,
thank you for your effort. So you hit a brick wall of sorts... I reckon that
- before you commit changes of this magnitude - it would be a good idea to use
EiffelTest at your site before committing anything to the repository.
I can see why you would want to have this implemented in Eiffel only, if only
to ease bug hunting.
On the other side, Cyril has done a lot to implement thread-local storage (TLS)
on the C-side. I'll have a look to see whether this can be used in the
C-runtime for deep_twin as well. Perhaps we'll end up with a thread-safe
deep_twin() that way.
