I've thought about this before too.  But, every time I've tried to do 
something like that with the flags, I get many errors in numpy and scipy 
because of the way contiguousness is actually used.  Somehow, I've never 
gotten the right check to allow additional striding arrays to work 
correctly.

The _IsContiguous
and _IsFortranContiguous

functions are what should be changed if anything is done.
