I think I can probably get around this issue by creating my own port struct
to hold the bytes and the opened byte port for pass through. Something
like:
(define-struct byte-port (bytes port) #:property prop:input-port 1)
Are there any issues (cost, synchronization, etc) with using port structs
this way that I need to think about?
Thanks,
