[mcclim-devel] Problems in reading with :timeout

I'm having some newb confusion about the timeout value in stream input functions, (read-gesture ...) etc. (read-gesture :timeout 0) always just returns NIL, while timeout values >0 don't seem to have any effect at all. For example, in the Listener (read-gesture :timeout 1) keeps blocking until some gesture is given. Another source of confusion is the :input-wait-handler. From reading the spec I got the idea that it should be called "continously" when there isn't any input in the given stream, but it looks like the function is never executed. Are these real problems or am I just missing something obvious?
