Python Ice/ami test failures

Failure corresponds with this code:

ice/python/test/Ice/ami/AllTests.py

Lines 790 to 796 in 45a69a1

	cb = FutureFlushCallback()
	f = b1.ice_flushBatchRequestsAsync()
	f.add_sent_callback(cb.sent)
	f.add_sent_callback_async(cb.sentAsync)
	cb.check()
	test(f.is_sent())
	test(f.done())

Seems to only fail with the collocated test case. I hit this with python_d on Windows in case this matters.
