Thanks.

I was wondering whether we should have a buffer object be the access
method.  That is, provide a new class, implementing the buffer
protocol, which provides "direct" access to inferior memory; it
could have a constructor accepting an address and a size.  Then,
explicit read/write calls would not be needed.q

Is this feasible?  Would it perform well enough?
