I believe PEP 418 (or at least the discussion) would benefit greatly
from a glossary to encourage people to use the same definitions. This
is arguably the Definitions section, but it should move either near
the end or (preferably) ahead of the Functions. It also needs to be
greatly expanded.

What is the purpose of the f_tstate field in the frame object?
It holds a borrowed reference to the threadstate in which the frame
was created.
If PyThreadState_GET()-frame-f_state == PyThreadState_GET()
then it is redundant.
But what if PyThreadState_GET()-frame-f_state != PyThreadState_GET(),
Hi all,
This is an update on the (so far PyPy-only) project of adding Automatic
Mutual Exclusion to Python, via STM (Software Transactional Memory).
For the motivation, see here:

The point is that [with STM/AME] your

Hmm, those 20% refer to STM, right? Without hardware

Given the existing brokenness I personally think that removing the BOM
