This might be what you have in mind, but note that this case could be supported generically from RPython (without hacking at the PyPy source): when the RPython program starts, simply copy all global variables. I think that this would also make a copy of the JIT and the GC. For example, the GC is controlled mostly by a prebuilt IncrementalMiniMarkGC instance, which is a global variable. It's actually very easy to do (it's done in STM for example) but at the cost of one extra indirection for every prebuilt constant access. Trying to reduce this cost is more challenging (but on the other hand probably too small to measure anyway). A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
