Are you considering reviewing the current state of multi thread support in python? I mean something like removing the need for the GIT :-) Regards, Rodrigo

The GIL? Well, speaking for myself, I never liked the necessity to have a GIL, nor did I like the idea of building free threading into everything. Personally, I would prefer not to support threads in that sense at all, but only microthreads/tasklets from the Stackless package, which is much cheaper to implement. In my model, real threads in that sense would not have locking problems in the first place, but they would much more look like disjoint processes. I would not let run multiple threads in one interpreter, but give every thread an extra interpreter, and have all threads strictly disjoint. Communication would then be an extra action, which has to be done explicitly, by passign read-only references or explicit copies for writing. That would remove the load to always lock threads against each other, or to make all vulnerable objects thread-safe. Well, that's how I had done it, probably. Without re-designing Python (which is one of our goals, avoid language changes), we have no chance. Either threads have to be left out for now, or we need the GIL, too. I don't think it should be a primary goal of MiniPy to solve the Python thread problem in the first place. I believe, after having a running MiniPy, it can be used to exercise different threading models, and this much easier than with the current C based version. I don't believe that Python's current thread model is the final word spoken. I would like to change it or to provide alternatives. This is a reason to have something like MiniPy, but not part of it. ciao - chris -- Christian Tismer :^) <mailto:tismer@tismer.com> Mission Impossible 5oftware : Have a break!
