 I've received an anonymous reply that addresses the
 flash writing limitations:

: The flash can not be used '32 bit word' wise.
: You could try to write 16 bytes at once (4x 32 bit word),
: but the number of partial writes per 512 bytes (the normal
: size) is limited (I don't believe this number is specified).
:
: Note the '16 byte'data should be properly aligned on 16 byte 
: multiples (but again the number of 'partial write'is limited 
: .. let's say .. 16 times or so :-) ).
:
: You may repost this info in the group - as long as you
: don't refer to me.

 Since counting the number of times I write to a location
 presents a new bag of trouble, I'll use the dumb algorithm
 of copy, modify, erase and write back.  Sigh.
