Title: clear up some references left lying around in tpool

this fixes the issue seen in the failing build https://travis-ci.org/eventlet/eventlet/builds/7725869 for me.

As this test is now hitting more than one thread in the threadpool it was exposing a bug whereby a tpool worker would keep some references lying around until next usage, which in this case was preventing cleanup of the db connections in the test tearDown.
