[Tutor] curses delwin functionality?

I had the same question, and I performed some simple experiments.

1) Re-assignment. I ran this and watched python's memory usage. It was  
completely flat.
for i in range(1,50000):
     stdscr.refresh()
     win = curses.newwin(10,1,0,2*2*i)
     win.bkgd(' ',curses.A_REVERSE)
     win.refresh()
     curses.napms(1)

It seems that python calls the underlying curses API  
delwin(some_window) when some_window goes out of scope. Thus, there is  
no need to call something like it explicitly.
Hope this helps.
