[Numpy-discussion] New may_share_memory function

In SVN there is a new function  may_share_memory(a,b) which will return 
True if the memory foot-print of the two arrays over-lap.

 >>> may_share_memory(a, flipud(a))

This is based on another utility function byte_bounds that returns the 
byte-boundaries of any object exporting the Python side of the array 

Perhaps these utilities will help (I know they can be used to make the 
who function a bit more intelligent about how many bytes are being used).
