Checks that chan produces the message v within timeout seconds, using description as a description of the expected message.

Checks that chan produces a message that matches the pattern pat within timeout seconds. pred acts like it does for check-match.(pred and timeout are optional, but I need to figure out how to show that in Scribble.)
