Do you know the details of the ABI compatibility issue?

The problem is that there's no 'hook' to associate this doc with.  We
can't say 'if you do so-and-so, take care to note that only the main
thread can use Guile', because there is no so-and-so - because
--without-threads is the default.

If we made --with-threads the default, we could say what you suggest
as part of the doc for --without-threads.

So I think we should do that - but preferably after solving the ABI issue first.
