You probably only need to call "wait" once. That blocks the thread until it gets a result, so it is more CPU-efficient than calling "poll" in a busy loop.
Since you open a separate pipe for "stderr" in script.py, but don't do anything with it, there could be a deadlock with the child writing to the stderr pipe versus the parent reading from "stdout" or waiting for the exit status.
I guess your script is an approximation of the "sos" application. I don't have time to understand everything it is trying to do, but I added some comments at <https://github.com/sosreport/sos/commit/2fcf5f0#r30410300>. |
