I would use "sync/timeout" or "sync/timeout/enable-break", like Sam said. I don't recall using "read-bytes-evt", but I am fond of "read-bytes-avail!" in conjunction with "sync/timeout"*. Would be interesting to see how efficiently one could handle a particular I/O profile using "read-bytes-avail!", "read-bytes!-evt", and "read-bytes-evt".
