[issue28165] The 'subprocess' module leaks roughly 4 KiB of memory per call

Xavion added the comment: It's easier to reproduce the issue if you use a timer (rather than a loop). The newly attached logfile was generated with the following code fragment. def fTest() : check_output("true") threading.Timer(1, fTest, ()).start() -- Added file:

[issue28165] The 'subprocess' module leaks roughly 4 KiB of memory per call

Xavion added the comment: I wouldn't have reported this if it was only happening *once*. I already have it in a loop; a new shell command is fired every second. The memory footprint increases by roughly 4 KiB *each* time. I monitor it via the following Bash script: while true; do

Antti Haapala added the comment: 3.5.1+ ubuntu; I run the Popen case in while True, and watch `top` - not a single digit changes in the memory usage (the last digit being the kilobytes). That the memory footprint increases *once* by 4KiB is nothing; please run this in a loop. --

[issue28165] The 'subprocess' module leaks roughly 4 KiB of memory per call

New submission from Xavion: Each time I run a shell command via the 'subprocess' module, I notice that the memory footprint of my program increases by roughly 4 KiB. I've tested the problem with two different slices of code; the result is the same in either case (long after the function
