<p style="color: grey"> Python recipe 576759 by <a href="/recipes/users/4170279/">Mike Kazantsev</a> (<a href="/recipes/tags/asynchronous/">asynchronous</a>, <a href="/recipes/tags/ipc/">ipc</a>, <a href="/recipes/tags/non_blocking_i_o/">non_blocking_i_o</a>, <a href="/recipes/tags/pipe/">pipe</a>, <a href="/recipes/tags/subprocess/">subprocess</a>). 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>
