Although I wouldn't like to see a dependency on other SRFIs, I think a
section treating compatibility with them would be useful.  Perhaps
something like the following after the "Standard Conditions" section?

--begin suggested section----------
Compatibility with other SRFIs:
------------------------------
SRFI-18, SRFI-21 and SRFI-23 define some standard conditions.  If a
Scheme implementation provides these SRFIs, it should use the following
definitions:

For SRFI-18 and SRFI-21:
   (define-condition-type &join-timeout &condition
     join-timeout-exception?)
   (define-condition-type &abandoned-mutex &serious
     abandoned-mutex-exception?)
   (define-condition-type &terminated-thread &condition
     terminated-thread-exception?)
   (define-condition-type &uncaught &serious
     uncaught-exception?
     (reason uncaught-exception-reason))

For SRFI-23:
   (define-condition-type &srfi-23-error &error
     srfi-23-error?
     (reason srfi-23-error-reason)
     (args srfi-23-error-args))
   (define (make-error-exception r a)
     (make-condition &srfi-23-error reason r args a))
   (define (error reason . args)
     (raise (make-error-exception reason args))
