The issue for me was whether my data structures would be longword
aligned or not, since longword-aligned data is sucked in faster on
020s and 030s.
 
The answer ended up being "heap blocks are longword aligned on CPUs
where it makes a difference." My thanks to the people who are
responsible for the Memory Manager behaving this way.
