This is definitely very interesting and helpful. I did some further
testing and noticed that the behavior differs between normal str strings
and unicode strings:

resident_size()

3780

a = ["%i" % i for i in xrange(2**22)]
resident_size()

239580

del a
resident_size()

4128    <-- Most memory returned to the os>>> a = [u"%i" % i for i in 
xrange(2**22)]

resident_size()

434532

del a
resident_size()R

401760  <-- Almost nothing returned to the os

there is a ticket concerning this, and patches: 
http://bugs.python.org/issue2321.

Notice who the people comment on and watching that ticket are?
