Hi all,
Starting from last night, the nightly builds of PyPy are able to run
this kind of code:

The idea is to link in the libpython.so, using cffi. Then you can use

I thought about another possible way to handle minor collections in

we no longer need to force minor collections after each transaction.
This is possible if we use a single coordinated nursery instead of one
per thread.
