I'm definitely for changing to `8bit` instead of `8byte`... again from a comment below, we changed from bytes to bits in a hurry and some names suffered from that.

As for the code, we should probably `float` cast the _ENTRIES_PER_8BIT to be safe from that one off!  Alternatively, we could `from __future__ import division` and change other places that expect integer division to the explicit int division operation.
