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?

slot_tp_del(), but while the latter had to cater to types
that don't participate in GC, we know that generators do.
That allows strengthing an assert().

same kind of thing.

not be tracked by GC. This fixes 254 of test_generators' refleaks on my
machine, but I'm sure something else will make them come back :>

Not adding a separate test for this kind of cycle, since the existing
fib/m235 already test them in more extensive ways than any 'minimal' test
has been able to manage.

using a custom, nearly-identical macro. This probably changes how some of
these functions are compiled, which may result in fractionally slower (or
faster) execution. Considering the nature of traversal, visiting much of the
address space in unpredictable patterns, I'd argue the code readability and
maintainability is well worth it ;P

 - In functions where we already hold the same object in differently typed
   pointers, use the correctly typed pointer instead of casting the other
   pointer a second time.

Looks like a libffi bug.
