Could anyone answer me some simple questions:
1) Is there any concurrency facility in Self (I didnt find it in the manuals).
2) Is there any time limit for Self to become a available comercial language.
3) In my point of view, reflective facilities in Self make it a good language fo r OODB. Is there any work in this area (OODB) for self.
4) Is any known software Enterprise (Sun, Microsoft, IBM, etc.) trying to release a comercial version of self.
Thank you in advance,

Paulo,
Here are the answers to your questions:
- Is there any concurrency facility in Self
Yes, Self supports lightweight threads and the object library includes a a preemptive scheduler, semaphores, etc. I/O operations block only the thread, not the entire Unix process, so other Self threads can continue to run. The scheduler is written in Self and thus could be modified to, for example, support priorities.
- Is there any time limit for Self to become a available comercial language
- Is any known software Enterprise (Sun, Microsoft, IBM, etc.) trying to release a comercial version of self.
Self is a research project. As far as we know, neither Sun nor anyone else has plans to make Self into a product. However, the current (free) system is quite stable enough to do useful work.
- In my point of view, reflective facilities in Self make it a good language for OODB. Is there any work in this area (OODB) for self.
No. If you do any work in this area please let us know about it!
Let me know if you have any further questions.
