On the other hand, it may be faster for the machine to access the native word size in the array when 64 bits.  On the other hand, the table would take less cache space if it were half the size.  Any opinions on that?  Should we force the tables to use a four-byte integer type?)

My opinion on these matters is that you should always benchmark it.
Preferably on more than one CPU.

Unless someone beats me to it I'll write a short benchmark code and
report results.
