At some point we added a way to do it (basically you can do it
yourself, by writing a one-line function in C and calling it). We no
longer do that: it's too much of a mess if you start ha
Well, I know that Python uses references, so that wouldn't be possible in
normal Python code without using stack inspection.
In RPython, which restricts all of that, it'd have to be another translator

Hey all, I wrote some threaded code and ran it under different version
of python, and unexpectedly high overhead is observed:
cpython 2.6.8. cpython 2.7.6, pypy 2.2.1: 14~53ms
cpython 3.3.4: pypy 2.1.0 beta py3 mode: <1ms
is someone here interested in getting to the bottom of it?
or getting pypy
