Make map() and filter() identical to itertools.imap() and .ifilter(),
respectively.
I fixed two bootstrap issues, due to the dynamic import of itertools:
1. Starting python requires that map() and filter() are not used until
site.py has added build/lib.<arch> to sys.path.
2. Building python requires that setup.py and distutils and everything
they use is free of map() and filter() calls.
Beyond this, I only fixed the tests in test_builtin.py.
Others, please help fixing the remaining tests that are now broken!
The fixes are usually simple:
a. map(None, X) -> list(X)
b. map(F, X) -> list(map(F, X))
c. map(lambda x: F(x), X) -> [F(x) for x in X]
d. filter(F, X) -> list(filter(F, X))
e. filter(lambda x: P(x), X) -> [x for x in X if P(x)]
Someone, please also contribute a fixer for 2to3 to do this.
It can leave map()/filter() calls alone that are already
inside a list() or sorted() call or for-loop.
Only in rare cases have I seen code that depends on map() of lists
of different lengths going to the end of the longest, or on filter()
of a string or tuple returning an object of the same type; these
will need more thought to fix.

Make it so that test_decimal fails instead of hangs, to help automated
test runners.

Fix the remaining failing unit tests (at least on OSX).
Also tweaked urllib2 so it doesn't raise socket.gaierror when
all network interfaces are turned off.

README
This directory contains only a subset of the Distutils, specifically
the Python modules in the 'distutils' and 'distutils.command'
packages. This is all you need to distribute and install Python
modules using the Distutils. There is also a separately packaged
standalone version of the Distutils available for people who want to
upgrade the Distutils without upgrading Python, available from the
Distutils web page:
http://www.python.org/sigs/distutils-sig/
The standalone version includes all of the code in this directory,
plus documentation, test scripts, examples, etc.
The Distutils documentation is divided into two documents, "Installing
Python Modules", which explains how to install Python packages, and
"Distributing Python Modules", which explains how to write setup.py
files. Both documents are part of the standard Python documentation
set, and are available from http://www.python.org/doc/current/ .
