I'm wondering if we really need a full 64-bit OS and all applications at all.
In [Open]Solaris, only the kernel and some apps are 64-bit, and the
rest is still 32-bit because being 64-bit doesn't give them any
I know it's out of scope of this discussion, but maybe instead of
having a separate full 32-bit and 64-bit versions of Ubuntu we could
try a Solaris way and make a one hybrid 64-bit/32-bit os?
