+    # fourth stage: determine which partitions are 100% unused.
+    # these can then be "blanked out"
+    bmask = (1<<len(plist))-1
+    for p in bitp.values():
+        bmask &= ~p

done, but ironically (because the elwidth=0b11 partition
is 4x24-bit) there *are* no unused portions in the
example.

next stage will be to add an example which does have
blank unused padding parts through all elwidths
