Due to the slowness of the test environment

Would be interesting if it's slowness, because it failed 2 times
on the debug runner but 5 times on the non-debug one. We'll see.

The code was landed on Feb 12, 2024.
It is actually 1 time with debug runner but 3 times on the non-debug 
one. 1 time with debug runner and 2 times with the non-debug runner 
happened in a 12 hours period.

The only failure in a debug run was causes by an unrelated issue:

https://netdev-3.bots.linux.dev/vmksft-net-dbg/results/467362/7-fib-tests-sh/stdout

(grep for UBSAN)

Basically the problems happens quite sporadically only in "fast" env. I
think it's worthy a deeper investigation (it sounds like a race
somewhere).

I guess/hope then raising the number of temporary and permanent routes
created by the relevant test-case could help making the issue more
easily reproducible.

Thanks,

Paolo
