Concerns over the performance of programs written in Python are often
overstated — for some use cases, at least. But there is no getting around
the problem imposed by the infamous global interpreter lock (GIL), which
severely limits the concurrency of multi-threaded Python code. Various
efforts to remove the GIL have been made
over the years, but none have come anywhere near the point where they would
be considered for inclusion into the CPython interpreter. Now, though, Sam
Gross has entered
the arena with a proof-of-concept implementation that may solve the
problem for real.
