"Because certain data objects may be constrained by the target computer
to lie on certain addressing boundaries, a structure object may contain
"holes," storage units that do not belong to any component of the
structure.  The holes would make equality tests implemented as a
wholesale bit-by-bit comparison unreliable..."
