Com-hypirion-io-clojure provides a set of features wrapped in java classes:

*pipe: establish a link between inputstream and outputstream, also supports
reader and writer.
*signalinterceptor: intercept posix signals before they are sent to their
signal handlers.
*revivableinputstream: allow canceling blocking read calls to streams
without closing them.
*consoleutils: set on/off echoing in the console.
common usage of this library includes: asynchronous zipping of data from two data sources, redirecting output and input to subprocesses and loggers, and sending messages to threads.
