I still don't like the _after_fork() implementation. Its O(n) where n
== number of threads the parent process had.
Very wasteful when the fork() was done in the most common case of being
followed by an exec and calling os._exit(). It won't

The end result is that the import system now only emits a RuntimeWarning

Is this still desired? If so, I have fairly long list of differences
that I could document. Or maybe, I could backport the _pickle module to
Python 2.6, which doesn't have as many differences.

New submission from Alexandre Vassalotti [EMAIL PROTECTED]:
The multiprocessing module modifies the global copyreg.dispatch_table to
extend pickling to several built-in types (mostly callable types). In my
humble opinion, this is unacceptable for a standard library module.

speedup of this patch confirmed. Also, it triggers the bugs mentioned
that have their own issues open. Once #2542 is fixed this should be

why not? it allows developers to migrate 2.x scripts one-by-one to
working 3.0 conformant ones while maintaining backwards-compatibility w/
existing 2.x scripts extension modules (eg. numpy, PIL, zope, ...)

Extension modules can use PyFunction_GetAnnotations() to access and

Another option is to eliminate the use of PyStructSequence and handle
the creation of a named tuple and a class with the methods in os.py.
Then stat() can just return a tuple and the Python code can create the
instances from that.
