-       Indeed, we should align it:

-         on 16 for 486
-        on 32 for 586, PPro - k6-III
-        on 64 for K7 (maybe for P3 too).
-       Because L1 and L2 caches are aligned on those values.
-       But I don't want to code such logic here!
-     */
-     /* Why 16?
-        because some cpus need alignment, for example SSE2 on P4, & most RISC cpus
-        it will just trigger an exception and the unaligned load will be done in the
-        exception handler or it will just segfault (SSE2 on P4)
