[Bug]: Timer-Leak in ConnectionCache

[chrisdutz]

What happened?

It seems that if the connection cache is used with low concurrency (The connection is returned to the pool without other threads waiting for it) a timer is started, that unfortunately never seems to be stopped. This results in more and more open threads accumulating until the first of the timers actually times out and canceles the connection.
