New submission from Kristján Valur Jónsson <krist...@ccpgames.com>:

Michael Foord reminded me of this issue recently.  It was discussed on pydev a 
few years back and met with limited enthusiasm.  I speak from experience in 
live production with EVE that this simple change saved us a lot of memory.  
Integral floating point numbers are surprisingly common, falling out of 
mathematical operations and when reading tabular data.  0.0 and 1.0 in 
particular.
