Indeed, nothing. We were not sure if FFI was working on it, but it turns out
that it was. The idea is to be aware if Eliot releases a threaded VM/FFI so
that we do not lock the VM (even if we have our micro-lock strategy when

We do not know. However, we will not spend time in Alien unless it is
working out of the box and integrated in all standard VMs.

Ahh ok, we didn't know. Thnkas.

Yes, the problem is that SqueakDBX as itself (the database driver), is MIT.
Thus, the repository is MIT. Glorp is LGPL. When we started (years after
SqueakDBX) with GlorpDBX, we found it easier to commit our changes to
SqueakDBX repo instead of the Glorp one (because not everybody may agree
with our changes).
The good news is that Alan Night was considering making Glorp MIT. I cc'ed
him to see if there are news.
