 in the Python community. There has been various attempts at removing it:
 some were successful, like e.g. in Jython or IronPython with the help of the platform, and some yet to bear fruit, like `gilectomy`_. Since our `February sprint`_ in Leysin,
 we've been on-and-off tackling directly the topic of GIL removal in the PyPy project.
+We believe that the work done in IronPython or Jython can be reproduced with
+only a bit more effort. Compared to that, removing the GIL in CPython is a much
+harder topic, since it requires tackling the problem of multi-threaded reference
+counting. See the section below for further discussions.

 to be guarded. PyPy only has the former problem; the latter doesn't exist,
 due to a different garbage collector approach.  Of course the first problem

+is a mess too, but at least we are already half-way there. Compare to Jython
+or IronPython, PyPy lacks some data structures that are provided by JVM or .NET,
