Call-with-port not closing the port in exceptional situations is a
shame.  As it is, the only thing you can do to close ports in
exceptional situations is to use dynamic-wind.  Nasty.

Why allow current-input-port to be a binary port?  I would not do that.
Likewise I don't see why read-u8 and friends would default to a textual
port.

Otherwise things seem fine to me.
