configure time. The current check is too strict and doesn't allow building
extensions that can only run on newer versions of the OS than the version
python was build for, that is python build for 10.3 or later and an extension
for 10.4. This patch relaxes this check.

This turned out to be a reimplementation of patch 1193190.

Remove translated code hidden inside a comment environment; latex2html gets confused and includes half of it anyway

the above command did not look for pyconfig.h, but the
bug is really in the look-up code: expecting to find it
in os.curdir is a rather fragile idea.

always reload the module (specifically, it doesn't reload if the module has
a 'test_main'.)

'python.org' when deciding what server to use for the timeout tests; getting
tired of seeing the test fail on all my boxes ;P This'll still allow the
test to fail for hosts in the XS4ALL network that don't have an 'xs4all'
hostname, so maybe it should use a fallback scheme instead.

prevent unreported regression.

exceptions that can't be raised any further, because (for instance) they
occur in __del__ methods. The coroutine tests in test_generators was
triggering this leak. Remove the leakers' testcase, and add a simpler
testcase that explicitly tests this leak to test_generators.

test_generators now no longer leaks at all, on my machine. This fix may also
solve other leaks, but my full refleakhunting run is still busy, so who
knows?
