Yes, this is correct.  byte-string is loaded first, binding
byte-string-hash to the srfi-13 procedure.  utf8 then passes that
*value* to a higher order procedure to create a new procedure, so
there is no circular reference.  Indeed, the test suite passes this.

There is a loop, but that's for a different reason.  When you don't
pass any position arguments it uses a shortcut case, and I
accidentally wrote "string-hash" instead of "proc" for that case.
I've fixed this, added it to the test suite and will upload the fix
soon.  Thanks for reporting it.

I'm sorry I haven't had a chance to look at your other problem, but
neither Felix nor I have been able to reproduce it.  I'll have time to
check it on a Mac this weekend.  However, this has nothing to do with
utf8, case-map is a separate optional module.
