Anything in use is in memory, but a stack in use that has not been 
opened is not listed among the openStacks (though of course it is listed 
among the stacksInUse).

Moreover, just last night I was working on my CGI library and found that 
  it works well when my script uses "start using..." at the top with no 
explicit "close stack..." or "stop using..." at the end.  Running top 
via telnet suggests that memory is reclaimed, and subsequent calls to 
the CGI all work.

There are many differences between using the engine as a CGI and as a 
normal GUI app, but at least in my tests on Linux at Dreamhost with v2.9 
it seems that termination does the sort of memory cleanup we'd expect.
