Could the delay not be the cause, but a side effect ?

Yes, that's probable. It might be possible that some interrupt got delayed too much, or that packets were completed in wrong order.

Do you have any idea why keeping my CPU busy removes the problem ?

I'd guess that an idle CPU needs a longer time to wake up. What CPU and what CPU frequency governor are you using?
