Hmm, my understanding is that each buffer can have its own display
table, buffer-display-table.  whitespace-mode has to modify this table
(or install an own one) if it wants to do buffer-local modifications.
So I think it modifies org-mode's table but doesn't override it.

My irritation is that by doing so, it does modifies some global state
that effects other buffers.

A short look into org.el shows that org-display-table is never made
buffer local, so this data structure is shared across all org-mode buffers?

The following hack seems to solve this problem:
