Printing to stdout, doesn't mean the data was actually written.
It depends on the buffering, so we need to flush.  This will hopefully
really fix the buildbots getting killed due to no output on the slow bots.

(since they won't trigger if zlib is already sucessfully imported); they
were found by grepping .py files, instead of looking at warning output :)

 - Warn-raise ImportWarning when importing would have picked up a directory
   as package, if only it'd had an __init__.py. This swaps two tests (for
   case-ness and __init__-ness), but case-test is not really more expensive,
   and it's not in a speed-critical section.

 - Test for the new warning by importing a common non-package directory on
   sys.path: site-packages

 - In regrtest.py, silence warnings generated by the build-environment
   because Modules/ (which is added to sys.path for Setup-created modules)
   has 'zlib' and '_ctypes' directories without __init__.py's.

are newer then fficonfig.py.

This may be a useful style question for the docs -- should examples show
the necessary imports, or should it be assumed that the reader will
figure it out?  In the What's New, I'm not consistent but usually opt
for omitting the imports.

- elaborate instructions for Cygwin support (closes SF #839709)

don't have an access on MIPS machines.  Will be tested by buildbot. :)

list resize, which overallocates.

list.extend tests (they were estimating half the actual use.)

tuples. Lots to be added, still, but this will give big-memory people
something to play with in 2.5 alpha 2, and hopefully get more people to
write these tests.

the one at the end.

After the patch (45590) to add extra debug stats to the gc module, Python
was crashing on OpenBSD due to:
	Fatal Python error: Interpreter not initialized (version mismatch?)

This seems to occur due to calling collect() when initialized (in pythonrun.c)
is set to 0.  Now, the import will occur in the init function which
shouldn't suffer this problem.
