Of course, sorry. But because I don't know how to read out Python's memory consumption from within python, these lines should be run successively in Ipython, so that one can see, how the 'Real Mem' system indicator grows each time. l = [28.1] arr = ones((1500,1500,3)) l.append(79.7) imshow(arr) l.append(172.0) imshow(arr) l.append(249.0)) l.append(249.0) imshow(arr) l.append(326.3)) l.append(326.3) imshow(arr) l.append(404.4) imshow(arr) l.append(482.4) This was run in an ipython session started with the -pylab flag. The numbers in the l array are the MBs I read of Mac's Activity Monitor for the Python task.
