It seems to me that the second case would be better served via a
more formally designed shared memory API.

As for the first case, that's just a performance hack.  True, some very
interesting examples have been given in which that performance hack has
been useful--but wouldn't it be better to work on improving the
performance of strings in general?  If an application really does need
the hack, wouldn't it be better for the author to write his own
extensions in C rather the cluttering up guile proper with what the
uninitiated might perceive as integral functionality?

Politicians and nappies should both be changed at regular intervals, and
for exactly the same reason.
