[SciPy-User] __sizeof__ disagrees with .nbytes

[Gabriel Gaster]

Run the following code:

from scipy import sparse
x = sparse.rand(100,10,.2)
print x.__sizeof__()
## 32 or 16, depending
print x.data.__sizeof__()
## 80 or 40, depending
print x.data.nbytes
## 1600

import numpy
print numpy.arange(200).__sizeof__()
## 80 or 40, depending
print numpy.arange(200).nbytes
## 1600

1. Why is nbytes different than __sizeof__ ?  I believe nbytes and do not believe __sizeof__. __sizeof__ should just be rewritten to default to nbytes.
2. It seems that the __sizeof__ methods need to be updated for numpy.array AND for scipy.sparse.

I'm happy to do this -- but before I do, I wanted to sanity check with the list.
Thanks.
