[issue13351] Strange time complexity when creating nested lists

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

In the case of 'lists' an object is being allocated each time through the inner loop.  In the case of simple_lists, no such allocation is being done.  Your timing issues are probably related to the memory allocation behavior of your system.
