.timeout() functionality does not work on payload processes with children about assert_cmd

What OS is this on and can you create a reproduction case to add to the tests?

When the child process is killed, I would expect the OS to close the stdio which would cause the reader threads to end

The file descriptor will be closed if there are no more processes attached to it, but if the initial payload process spawns a child process before being killed, and that child process inherits the standard out of the payload process, then after the kill there will still be a process attached to the stdout fd, so it will not be closed.

I can try to put up a test for this, but I probably won't get to it for a while.

If we cancel the read threads, what would be keeping us from leaking the child processes? I feel like the main issue here is that those aren't being killed and not us continuing to read from them.
