Preferences - "Leave tasks in memory while suspended?", when unset, should remove previously-suspended tasks from memory

[JacobKlein]

I found this while testing a recent Alpha:

In my scenario, I had "Leave tasks in memory while suspended?" set to Yes for quite a while.  Several hours later, after many scheduling periods, several tasks were suspended in memory, as expected.

However, when I changed the setting to No and suspended processing, only the tasks that had been processing during the change, were removed from memory.  The previously-suspended tasks were still eating memory.

If possible, "Leave tasks in memory while suspended?", when unset, should remove previously-suspended tasks from memory.
