For what it's worth, I have a little Scheme-based html generation
program (don't we all :) that suffered from this very problem.
I ended up dropping string-append completely.  I built a tree of
strings, opened output to the target file, and just walked the tree
with `display'.

Perhaps this is what you meant by implementing string-append/shared
at a higher level.  That's pretty high, though.
