Subject: 64 bit VS 32 bit

Hi,

Having just switched to a AMD dual 64bit  processor,  I noticed
that Ruby is obviously NOT tuned for a 64 bit processor.  This is
quite understandable and and not a complaint.

Are there plans, probably in Far Distant Future, to improve
memory usage in a 64 bit world?

Just as an example,  on 64 bit machines the basic object structure
doubles to 40 bytes.  Thus,  the heap structures double in size!

This is just an issue we should probably think about in the future! 

Of course,  as the cost of memory decreases,  probably  a minor one.
