Seems to work OK on my Mac Pro, although I hardly put it to
the test.  Are there any specific commands that you would want
 me to try or that  I might expect to run faster on the 64 bit
version?  Perhaps some operations with large matrices?

I notice the following when I check the precision of double:
sage: RDF.prec()
53

This is the same result I get when I execute this command on
my 32 bit version.  I expected this, since I've noticed the same
behavior in 64 bit Mathematica, Matlab, and C, but it makes me
wonder why we should be excited about 64 bit systems.
