3.3.2 patch: minor session cleanup issue

In 3.3.2, when a client session’s connection closes while the session is still present, I don’t see anything that cleans up the routing table entries for the session. This patch does the cleanup. The trunk code looks fine in this regard, so if no further releases are planned before a release from trunk, this patch can be ignored. I don’t actually have explicit instructions for reproducing problems from the left-over routing table entries (other than a small memory leak). I could even be wrong about them being left over, though if so, I can’t find the code that would remove them.
