So I did that. In the test program
"""
if 1:
L = [u"abc%d"%i for i in xrange(1000000)]
else:
L = ["abc%d"%i for i in xrange(1000000)]
raw_input('L is built')
del L
raw_input('L is deleted')
"""
the process size grew to 46MB using regular strings, and to 69MB using
Unicode strings. The second time the test program pauses shows another
difference: pymalloc never gives small-block memory back to the system free
now, so the process size only shrunk by 4MB (for the list guts) after
deleting L when using regular strings. The process size shrunk by 42MB when
using Unicode strings.
