So it always increments the very first process with WID 8, but all others are staying 0.

So if I increase the number of curl requests to let's say

for i in {1..5}; do curl http://localhost:5050/admin/login/ &>/dev/null; done

then I do get process with 2 processes (visible at Linux top 98% one and around 17% another) doing the work, while all others are staying iddle with 0% CPU utilization, but still uwsgitop shows 0 for everyone but WID 8.

Am I missing something?
