We're starting to build in 64-bit mode to have more heap space available 
(our effective limit is a little over 2G for 32bit). The downside is 
that all pointers also double in size and the executable gets a lot 
larger. Which causes an even larger memory footprint ... sad to say, we 
have a couple of dev machines thrashing because there's on average 
around 150G in swap after we fill up the 256G of DRAM. Sure, having a 
64-bit processor is cool, but not so sure they should blindly build 
64-bit processes "just 'cause".
