Then insert some debug prints into your program.  I.e:

 while (1) do
   print(CUR)
   row = CUR:Fetch()
   if not row then
   ...

and a similar printf in the GC-routine to see whether the GC
really collects an item still stored in a global.  I doubt it...

Ciao, ET.

PS: You are aware that your examples are using global variables?
I see no local statement...
