Pub/sub leaks memory

Description

The following code will cause OOME:

(It grows slowly: to see the OOME in a reasonable amount of time, either give JVM very small
memory like 64m, or remove the timeout step.)

I tried to profile the code, and the reason seems to be that even though I
unsubed the channel from the port, something is still retained which causes
the heap to be used up.
