[racket] Test for async-channel being full

I think that you roll your own syncronization primitive, instead of using
an async-channel. Create a thread and have a little loop that gets whatever
the events you want to support (e.g., get, put, is-full?) and then work
directly at this level. This is the beauty of CML; writing such things is
easy.
