Description
When calling (read-line) from lein repl or ccw repl, waiting around four minutes (on my machine),
evaluating any form causes the following exception:
ERROR: Unhandled REPL handler exception processing message {:code (+ 1 1), :id 08e30b70-ab0f-4a47-8937-3c040ce06f4f, :ns user, :op eval, :session 916200cc-e476-4ac4-98f6-76057a9020be}

While googling a bit on this and without concrete knowledge of the implementation in nrepl,
it seems like closing a thread that wrote to PipedWriter, before closing the writer or writing to it from another thread,
causes PipedReader#ready to throw that exception.
