The existing Stackless<br>PyPy, which does no C stack manipulation, doesn't work with the
JIT<br>without a lot of careful work. This solution is deprecated now. The<br>new solution, which does C stack manipulation, works with the JIT out<br>of the box. Both solutions are "implementation details" only; you get<br>the same tasklet/greenlet API to work with.<br><br>> So will PyPy JIT work with gevent which is based on libevent (and soon to be<br>> libev)?
