Read this: http://portal.acm.org/citation.cfm?id=1176753 It has a discussion about the relation to Squeak at the end. > 2. The main reason PyPy decided to implement GIL was for the c > extensions to run unchanged. There is no "official" reference for this. The reason why we have a GIL is because doing anything else is significantly harder, and would require a GC that works well with threads. This is a non-trivial task. In general, if you are looking for more "scientific" reference, look here: http://codespeak.net/pypy/dist/pypy/doc/extradoc.html There is also an article about to be published about the main JIT optimization here: http://codespeak.net/svn/pypy/extradoc/talk/pepm2011/bolz-allocation-removal.pdf Cheers, Carl Friedrich _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
