Description

from proton.utils import BlockingConnection
connection = BlockingConnection(url)
sender = connection.create_sender(queue_name)
sender.send(message)
sender.close()
connection.close()

Leaves a CLOSE_WAIT lingering indefinitely every time, leading to ValueError: filedescriptor out of range in select() when ulimit is reached.

python_qpid_proton-0.30.0-py2.7-linux-x86_64 talking to ActiveMQ 5.14.5. Problem also occurs in 0.29.0, 0.28.0 but not in 0.27.0.

Debug log attached.
