Better safe than sorry...

Is it possible that a chain entry pointer has bit 1 set on architectures
(e.g. m68k) where the natural alignment of 32-bit quantities is _2_ bytes,
not 4?

Better make sure that such alignment never happens... But no, I don't 
think it will, since these things would generally always have to be 
allocated with an allocator, and the *allocator* won't return 2-byte 
aligned data structures.

How about stack allocations?
