reader-close and writer-close seem missing from the current draft. It may also be good to note that the 'close' procedure passed to make-simple-reader/make-simple-writer is called only synchronously, when reader-close/write-close procedure is called. (Another option is to allow an implementation to call 'close' when the reader/writer is about to be GC-ed, but that'd make it difficult to write portable code using srfi-68). --shiro
