Summary: MemoryError with a lot of available memory - gc not called

Initial Comment:
Also the gc behavior is consistent with the
documentation, I beleave it is wrong. I think, that Gc
should be called automatically before any memory
allocation is raised.

Example 1:
for i in range(700): 
   a = [range(5000000)]
   a.append(a)
   print i

This example will crash on any any PC with less then
20Gb RAM. On my PC (Windows 2000, 256Mb) it crashes at
i==7.
Also, this example can be fixed by addition of a call
to gc.collect() in the loop, in real cases it may be
unreasonable.
