I run a simple Python script in a docker container (single process, no multiprocessing or multithreading).
When looking at it with ps (one instance):
root@srv ~# ps -ef | grep homemonitor
root 17858 17824 0 19:43 ? 00:00:00 /bin/sh -c python3 homemonitor.py
root 18080 17858 12 19:43 ? 00:03:04 python3 homemonitor.py
When looking at it with top (one instance):
(...)
26307 root 20 0 2782476 37300 10868 S 4.3 0.5 0:04.56 python3 homemonitor.py
(...)
When looking at it with htop (multiple instances, among other processes I removed here):

Why is htop display do different? What do the multiple processes actually mean in that display?
