replaced by PAGESIZE=tuneable) ...
[1]=Yes, I know... some hardware like the original UltraSPARC-3 and
SPARC64 CPUs won't like that much...
We tried in during Solaris 10 development... but there's too
much code out there that just breaks. The programmers made implicit
assumptions about the approximate size of a page, and that was that.
