create-temp-file uses temp-file-iterate, so we can't change the former procedure willy-nilly. 

Just rename the SRFI 170 version to something else.  Unlike create-directory it's not a name we have to keep.
I think this is best placed at the end of the procedure definition line, something like, maybe with some additional symbol after "(procedure)":

(file-info fname/port [chase?]) → file-info-record  (procedure)  (POSIX stat)

Works for me.
