it's a test that very seldom fails in some cases no matter what, as it's
checking reference counts on objects that are expected to be garbage
collected without any cycles. A failure of this test is not strictly a
"bug", it just refers to connections or cursors that are not collected
immediately. if it is persistent and only occurs with pg8000 then
there might be some cursor cleanup issue going on.

Hi, I found the following SQLAlchemy test fails:
FAIL test/engine/test_pool.py::QueuePoolTest::()::test_queuepool_close
with the stack trace:

The versions I'm using are:
platform linux -- Python 3.4.0 -- py-1.4.26 -- pytest-2.7.0
I ran it against the tip of the master branch
72329433e78e57c8589e4797df523bb598190b64
and the command I ran was a straightforward:
py.test test/engine/test_pool.py::QueuePoolTest
I'm sure I'm doing something really obviously wrong, but I'm not sure
what, so I'd be grateful if anyone can help. Btw, it was the only test
that failed when I ran the entire suite.
Thanks,
Tony.
