Revision 21. </p> <p>A coroutine-based wrapper for subprocess.Popen that uses asyncore to communicate with child processes asynchronously. This allows subprocesses to be called from within socket servers or clients without needing a complicated event loop to check both. Uses <a href="http://code.activestate.com/recipes/576965/">recipe 576965</a> to provide the asynchronous coroutine framework, <a href="http://code.activestate.com/recipes/576967/">recipe 576967</a> to provide asynchronous pipes, and <a href="http://code.activestate.com/recipes/577600/">recipe 577600</a> to provide multiple alarms.</p>

Revision 2. </p> <p>Just stumbled upon the need to move data chunks between subprocesses in a non-linear way with some logic in-between, so tee(1) and fifo(7)'s weren't too good option. Inspired by 440554, but rewritten from scratch to remove unnecessary delays due to sleep(3) calls and suboptimal try/sleep-based polling.</p>
