The mmap module is useful also for larger amounts (>4k say).
mmap's are individually free-able so they don't fragment your memory.
http://docs.python.org/library/mmap.html
Eg create a 1 GB anonymous mmap, access it and then delete it
>>> from mmap import mmap
>>> a = mmap(-1, 1000000000)
>>> a[0]
'\x00'
>>> a[0] = 'z'
>>> a[999999999]
'\x00'
>>> a[999999999]='q'
>>> a[999999999]
'q'
>>> del a
