thx for responding (I was about to send the question to twisted mailing list too ;-). still would like to find out why it is happening (now FD_CLOEXEC narrowed may yahooing/googling searches). While realize that file descriptors are shared by forked processes it is still weird why the port moves to the child process once parent gets killed. what it the parent got multiple subprocesses. Plus it is kind of unintuitive os.system does not protect from such behavoir which is for me more an equivalent of like issuing a ne wcommand/ starting a process from the shell.
