Your suggestions about "exit" are certainly very true, but as you correctly
point out, the semantic issues of a "standard" "exit" are rather unclear,
and IMHO it would be better to leave it out alltogether. 
Defining your own "exit" is trivial, and if the user makes use of "dynamic-wind", 
the she should be aware of the consequences and write her code (and her
unwinding thunks) carefully (she has to do it anyway). 
Moving the responsibility to SRFI-22 makes it unnecessarily complicated, 
for very little gain.
