I still do not understand why Archiveopteryx runs stably in some places and crashes every few hours or days in others.

It's just just a question of platform-specific bugs. We've seen it too many times: A bug hits some people, not others, for reasons I do not understand even after fixing the bug. As a result, some people see aox working really well, others really badly, and I have no way to explain why this is so, and see no pattern I could use to improve testing or avoid these bugs.

It's very frustrating.
