Hello,

I can understand this. 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.
