Hi Duncan,
I don't think so. It seems that the coding in childapp.py did not really
change from 1.7.3 to 1.7.5. (At least the bits which are intresting here.)
In fact, the wait() function correctly detects that the child was killed. This
is not the problem.
However, afterwards, the poll() function does not detect any more that the
child process was killed. IMHO, this is because the inconsistency between
os.waitpid() and subprocess.Popen.poll() I have tried to describe in my
initial post.
Regards,
Thorsten
