FYI, there are both 32 and 64-bit JVM installs for Windows, and JRuby
will run fine out of the box on either. Regardless of 32 or 64-bit,
JRuby always has 64-bit Fixnum and Float, so the main thing you get
from a 64-bit JVM is a larger addressable memory space (anyone out
there with 50GB Ruby applications?)
