Established associations not timing out

[scaramallion]

Description

Association should end with abort once commands have been completed and timeout expires.

Expected behaviour

At the end of a script that requested an association the association should abort unless already ended through assoc.release() or assoc.abort() when the timeout ends.

Actual behaviour

A requested association stays established, timeouts don't appear to have any effect. Seems to work OK with acceptors.

Steps to reproduce

Request a new association, send a DIMSE-C service request and don't release it.
