[issue24862] subprocess.Popen behaves incorrect when moved in process tree

[Andre Merzky]

Andre Merzky added the comment:

Looking a little further, it seems indeed to be a problem with ignoring SIGCHLD.  The behavior has been introduced with [1] at [2] AFAICS, which is a response to issue15756 [3].  IMHO, that issue should have been resolved with raising an exception instead of assuming that the child exited successfully (neither is true in this case, not the 'exited' nor the 'successfully').
