i have started about 20 processes using
subprocess.Popen(command,stdout=PIPE)
and have gotten EOF on all their pipes. now i want the parent script to wait for all of them to exit. for various reasons some could take several minutes to exit. i'd like to allow up to 5 minutes for the whole bunch. is there a way to wait for them all as a group with just a single timeout? normally i would just for loop through the list of objects i got from Popen and call each.join()
. but putting the 300 second timeout in there could end up being a long time if several are slow. is there a better way to wait for them all while giving up after 5 minutes?
