Optionally, you can also automatically debug-enable sub-processes created withmultiprocessing, viasys.executable, and (on Posix) withos.fork(). Automatically debugging child processes is off by default since it can be confusing or unwanted in some code bases. It can be enabled with theDebugger>Pr...

The multiprocessing module's Manager* classes can now be passed a callable that will be called whenever a subprocess is started, along with a set of arguments that will be passed to the callable. (Contributed by lekma; bpo-5585.) The Pool class, which controls a pool of worker processes,...
Some significant new packages have been added to the standard library, such as the multiprocessing and json modules, but there aren't many new features that aren't related to Python 3.0 in some way.Python 2.6 also sees a number of improvements and bugfixes throughout the source. A search ...
