And it might definitely be PEBKAC. But what I see is real and I do not thing I've screwed my scripts so much. Attached is simple reproducer I was able to get from my scripts. If you will test it you will have to change base url in fetchData.sh. When I run this script for a while I see a lot of 'zombie' bash, sleep and wget processes in RamMap (they do not show in task manager). I can provide screenshot. If that would matter I run this scrips from truecrypted disk.
