- Thanks to Scott David Daniels, a subtle bug in how the zlib

extension implemented flush() was fixed. Scott also rewrite the
zlib test suite using the unittest module. (SF bug #640230 and

Backport candidate I think.

Get rid of relative imports in all unittests. Now anything that
...
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)

[ #403753 ] zlib decompress; uncontrollable memory usage
...
Mostly by Toby Dickenson and Titus Brown.
Add an optional argument to a decompression object's decompress()
method. The argument specifies the maximum length of the return
value. If the uncompressed data exceeds this length, the excess data
is stored as the unconsumed_tail attribute. (Not to be confused with
unused_data, which is a separate issue.)
Difference from SF patch: Default value for unconsumed_tail is ""
rather than None. It's simpler if the attribute is always a string.
