--- Comment #3 from Zakhar <alainb06 at free.fr> ---
Hi, I would need some help, or at least a pointer (link) to instructions on how
to try that.

What I tried (the above) can be reproduced 100% of the time with the latest
Ubuntu 18.04 and its 4.15 (generic) kernel. The behaviour (several 10 sec time
outs) existed since kernel 4.8

I have already done patch of my own on packages like tor, and even done my own
packages, but never played with the kernel...
