Also, the GIL is always released when doing I/O. - Past efforts to create a "free-threaded" interpreter (one which locks - shared data at a much finer granularity) have not been successful - because performance suffered in the common single-processor case. It - is believed that overcoming this performance issue would make the - implementation much more complicated and therefore costlier to maintain. - + As of Python 3.13, the GIL can be disabled using the :option:`--disable-gil` + build configuration. After building Python with this option, code must be + run with :option:`-X gil 0 <-X>` or after setting the :envvar:`PYTHON_GIL=0 ` + environment variable.
