Thanks :-)

Brain error on our side: the gc_pypy.dll is the dll of the Boehm garbage
collector, which you would need to compile yourself (which makes
precompiled binaries a bit useless :-) ). We updated the zip file, would
you mind checking whether it works better now?

Relatively soon. The hard bits of that are done, the JIT compiler
generator is in a pretty good shape, we need to apply it to more parts
of the PyPy Python interpreter. There are some non-coding related
reasons why we are not doing it _right_ now: we still need to write some
EU-reports (about the JIT for example) then we will need a while to
recover from the EU project.
