I've inserted the results of my test in this message. First the status
before the test, then the status after the test. Also I've used mozilla
as memory buffer. When the system fails and I close an application, like
mozilla, I can execute commands again. 
As you can see, ps shows no additional processes or defunct or zombie
processes. I've used the task manager to make a list of all processes
sorted by memory like you said. I can see the processes appearing and
disappearing in the task manager list, yet the memory usage is still
rising.
