Hi everyone, Will CLPython have a global interpreter lock? Will it allow different threads to touch Python objects simultaneously on different cores?
Thanks, Anand

My impression is that there is no need for a global lock: if CLPython were running in an SMP-capable Lisp implementation then multiple threads could execute Python code concurrently. But for that to work correctly, first many parts of CLPython must be made thread-safe. I've not given this any attention yet.

Thanks, it will be great to have a fast, SMP-capable Python implementation someday. Another question: are you planning on providing a Python-C API, so that packages with compiled extensions can run on CLPython? Cheers, Anand

No, there are no plans for implementing the C API. Actually I doubt it is practically possible, given the differences in e.g. object representation, garbage collection and exception handling.
